A.) If Grace and Claire’s parents each invested $7,600 into a college savings account when the girls were born, how much money will each girl have for college when she turns 18? Explain.

Answer/Explanation:

For Grace, I plugged in 18 for x.

Work:

y= 1000(18) + 7600

y= 18000 = 7600

y= 25600

For Claire, I had to first find the slop by using rise over run.

11600-10000/3= 800

So the formula for Claire is y= 800x + 7600 and then you just plug in 18 for x.

Work:

y= 800(18) + 7600

y= 14,400 + 7600

y= 22,000

Therefore, Grace would have $25,600 at the end of 18 years old and Claire would have $22,000 when she turns 18 years old.

                 I hope that helped you or anyone else!! :)

A) using y=mx+b find the slope between two points given (y2-y1) /(x2-x1) which will be the m value. The b value is the y intercept, i.e. the y value when x is 0 or the amount of money when they are born. After finding m and plugging in 7600 for b, substitute 18 for x since that is the age. Then solve for y=slope(18)+7600 and y will be the the amount of money at 18.

B) positive correlation. The slope is positive, i.e. The money is increasing with time, not decreasing.

bekas [8.4K]

Jeff should purchase 25 , 2 ounce box and it will cost him $27.5 .

<h3>What is an ounce ?</h3>

Ounce is defined as 1/16 part of a pound.

It is given that

price of a 2-ounce box is $1.10,

a 16-ounce box is $8.98

a 32-ounce box is $17.98.

As Jeff wants to purchase total 48 ounce chocolates , the box which is more cheaper has to be determined  

The price of 1 ounce in a 2 ounce box is $1.1 /2 = $ 0.55

The price of 1 ounce in a 16 ounce box is $8.98 /16 = $ 0.56

The price of 1 ounce in a 32 ounce box is $17.98 /32 = $ 0.56

Therefore Jeff should purchase 25 , 2 ounce box and it will cost him $27.5 .

Todd earned some money doing chores. He spent one-fourth of his money see a movie. Then he spent $6.00 on popcorn and drinks. Wh
Vsevolod [243]

Answer: Todd earned $40 mowing the neighbor's lawn.

Step-by-step explanation:

Let x represent the amount of money that Todd earned, mowing his neighbor's lawn.

He spent one-fourth of his money see a movie. It means that the amount spent in seeing a movie is x/4

Then he spent $6.00 on popcorn and drinks. It means that the total amount spent is

x/4 + 6

The amount left would be

x - (x/4 + 6) = x - x/4 - 6

When he went home, he had $24.00 left. It means that

x - x/4 - 6 = 24

x - x/4 = 24 + 6

x - x/4 = 30

Cross multiplying by 4, it becomes

4x - x = 120

3x = 120

x = 120/3

x = $40

could 7.2 inches and 28 inches be the diameter and circumference of the same circle? Explain why or why not.
Minchanka [31]

Answer: The diameter 7.2 inches and circumference 28 inches of the same circle could not possible.


Step-by-step explanation: Given diameter of the circle = 7.2 inches.

Circumference of the circle = 28 inches.

Formula for Circumference of the circle = πd, where d is the diameter of the circle.

Plugging value of d in formula, we get

Circumference of the circle = π(7.2).

Plugging π= 3.14, we get

Circumference = 3.14 (7.2) = 22.61.

22.61 is smaller than given circumference 28 inches.

<h3>Therefore, the diameter 7.2 inches and circumference 28 inches of the same circle could not possible.</h3>

The table shows the cost of buying x tickets to a school play. Buying Tickets Number of Tickets, x 2 5 10 13 Cost, y $8.50 $21.2
Naily [24]

Answer:

y-intercept is zero

Step-by-step explanation:

The general equation of the line passing through the points is

y = mx + b

where m is the slope and b is the y-intercept

We can pick any two points to get the slope of the line;

m = (55.25-8.5)/(13-2) = 46.75/11 = 4.25

So partially , the equation will be;

y = 4.25x + b

To get b , substitute any point and use its x and y values

We have (2,8.5)

8.5 = 4.25(2) + b

b = 8.5-8.5

b = 0
