Julia sold 24 candy bars during the first week.

dalvyx [7]

So Julia sells 24 candy bars the first week. The second week she sold 6 more than 2 times the number of the first week. So the equation would be 24•2+6 = 54. So 54 would equal the amount she sold the second week. The third week she should 4 less than 1.5 times the number of the second week. The equation to find the third week would be 54•1.5-4=77. To find the amount total of all three weeks you would add 24, 54, and 77. The answer is 155 total candy bars.

Hope this helps!! :)

A real estate sales agent receives a salary of $250 per week plus a commission of 2% of sales. Write an

Tcecarenko [31]

Answer:

The equation y=0.02x+250 gives the weekly income y in terms of sales x.

Step-by-step explanation:

Given,

Weekly salary of real estate agent = $250

Commission rate = 2%

Let,

x be the sales per week.

y be the total weekly income.

Amount of commission = 2% of sales per week

Amount of commission =

Amount of commission = 0.02x

Total weekly income = Amount of commission + Weekly salary

What is the domain and range of the problem? How many beats will she have in half an hour? Is the graph discrete or continuous?

san4es73 [151]

From the statement, we know that Miss Butterkey's heart rate is 80 beats per minute.

So the ratio of beats per minute is:

$r=80\cdot\frac{\text{beats}}{\min }\text{.}$

The number of beats as a function of time is given by the product:

$b(M)=r\cdot M\min =80\cdot\frac{beats}{\min}\cdot M\cdot\min =80M\cdot\text{beats.}$

Where t is the time in minutes.

(0) If we define:

• M = # of minutes,

,

• b = # of beats after M minutes.

Using the equation of b(t), we have:

$b=80M\text{ beats }\Rightarrow M(b)=\frac{b}{80}\text{.}$

(1) Domain and range

If we consider the independent variable as the number of minutes M, the domain is:

$\text{Domain = 0, 1, 2, 3, }\ldots\text{.}$

If we consider the dependent variable as the number of beats b, the range is:

$\text{Range = }0,80,160,240,\ldots\text{.}$

(2) # of beats after half an hour

After half an hour the time is t = 30 min. Replacing this value in the equation of b(t), we get:

$b(30\min )=80\cdot\frac{beats}{\min}\cdot30\cdot\min =2400\text{ beats.}$

(3) The graph of heartbeats as a function of the minutes is discrete. That's because we can only have an integer number of beats.

(4) Labels of the graph

• horizontal label: number of minutes M,

,

• vertical label: number of beats b.

(5) Graph

Answers

• (0), M(b) = b/80

,

• (1) ,Domain = 0, 1, 2, 3, ... , Range = 0, 80, 160, 240, ...

,

• (2), b(30 min) = 2400 beats

,

• (3), The graph is discrete.

,

• (4) ,Horizontal label: # of minutes M, Vertical label: # of beats

,

• (5), Graph

Sheila bought burgers and fries for her children and some friends. the burgers cost $2.05 each and the fries are $.85 each. she

jeyben [28]

Let's have B stand for burgers, and F stand for fries.
2.05B+0.85F=$19.10 - This equation is set equal to total price.
B+F=14 - This equation is set equal to total number of items.
Subtract the F in the bottom equation.
B=14-F
Put this in place of B in the first equation.
2.05(14-F)+0.85F=19.10
Make sure you distribute the 2.05 properly, over both the 14 and the F.
28.7 - 2.05F+0.85F=19.10
Collect like terms for the F values.
28.7 - 1.2F=19.10
Subtract 28.7 from both sides.
-1.2F=-9.6
Divide by -1.2 on both sides.
F=8
Put this value in place of F in either equation.
B+8=14
B=6
So F=8 and B=6.
