For monthly payments, monthly interest, i = APR/12=0.03/12=0.0025
Time period, n = 12
Monthly payment, A = $150

Future value
= A((1+i)^n-1)/i
= 150((1.0025^12-1)/.0025
= 1824.96 (to the nearest cent)

Dr. Hoover, a pediatrician, has 3 annual checkups and 2 sick visits scheduled next Tuesday,
Jet001 [13]

Dr. Hoover allot his time on Tuesday for an annual checkup is 147 minutes and for a sick  visit is 42 minutes ​(Total 189 minutes)

On Wednesday appointment,  he allot his time for an annual checkup is 147 minutes and for a sick  visit is 21  minutes ​ (Total 168 minutes)

solution

Let us assume, minutes for annual checkup denoted as x and

minutes for sick visit denoted as y

The equation of Tuesday visit is       3x + 2y = 189 minutes ------ 1

The equation of Wednesday visit is    3x + 1y = 168 minutes ------ 2

by changing the signs of the equation 2  and  subtract it from the equation 1 we will get   1y = 21 minutes

to substitute y =1 in the equation 2 we get

3x + 2(21) = 189

3x + 42 = 189

3x = 189 - 42

3x = 147

x = 147 ÷ 3 = 49 minutes

then now we have substitute both x = 49 and y= 21 in equation ----- 2

we will prove that 3x + 2y = 189  = 3 (49) + 2(21) = 189 147+ 42 = 189 minutes

so the Tuesday appointment , the time allotted for an annual checkup is 147 minutes and for a sick  visit is 42 minutes ​(Total 189 minutes)

On Wednesday appointment,  the time allotted for an annual checkup is 147 minutes and for a sick  visit is 21  minutes ​ (Total 168 minutes)

At Greg's Gas Station premium gasoline costs $0.14 more per gallon than regular gasoline . If Mr. Adams spent $36.25 on 12.5 gal
Maslowich

Answer:

Step-by-step explanation:

At Greg's Gas Station premium gasoline costs $0.14 more per gallon than regular gasoline .

Let the cost of regular gasoline be $x per gallon, then the cost of premium gasoline per gallon will be x + 0.14

If Mr. Adams spent $36.25 on 12.5 gallons of regular gasoline, it means that 12.5x = 36.25

x = 36.25/12.5 = $2.9

The cost of regular gasoline is $2.9 per gallon

Therefore, cost of premium gasoline per gallon will be 2.9+ 0.14 = 3.04

if he bought 12.5 gallons of premium gasoline instead, he would have paid

12.5× 3.04 = $38

The amount that he would have spent more will be

38 - 36.25 = $1.75

Given the following graph of a system of inequalities, the point (3, 2) _____________.
uysha [10]
That point does not satisfy either inequality. 

You can tell it does not satisfy the first portion, due to it being under the shaded line. Secondly, the dotted line goes through it, but that fact that it is dotted makes it not included.

What is 2/5 plus 1/3
leva [86]
First, you need to get the denominators (the bottom number) the same.  The smallest number to get them to is 15.

So, what you need to do is take 2/5 and multiply the bottom by 3 to get 15, and since you did it to the bottom, you need to do it to the top too.   So you would get, 6/15.

Then, for 1/3, take the bottom number and multiply it by 5.  Then, since you did it to the bottom, do it to the top as well.  You would get 5/15.

Then, you need to put them side by side.  You don't add the bottom, so your denominator would remain 15, but your numerator (top) would get added.

<u> 6</u> + <u>5</u>     =   <u>11</u> 
15  15         15
