90/12=7.5.
so.....
7.5 times 15 is 21.
That added to the orginal amount equals to : 111.
How much the athletic director will pay to buy 15 more sun visors is $111.

Answer:
142 miles
Step-by-step explanation:
We are given the situation that Jill measured the distance from the western border to the eastern border in inches. And we are being asked how many miles is the actual distance.
So first , lets look at what we have.
The inches : 3.375
and our reference point
1 inch = 42 miles
We first look at the reference point, if 1 inch is 42 miles, how much would be 3.375 inches?
Multiply 3.375 by 42
==> 141.75 miles
Now the last sentence asks us to round the nearest whole number.
So look at the number next to one in the ones place and we see that the number is greater than 7, so we round up. Leaving us with the answer :
142 miles
The area of a parallelogram can be obtained by multiplying the length of the base by the height. Although no diagram is given, let us assume values of the base and height that would yield one of the choices as answers. Let us say that parallelogram MATH has the following values:
base = 6 m
height = 11 m
Area = base * height = 6 * 11
Area = 66 m^2
Therefore, the answer is B.
First term a1 = 6+5 = 11
second term = 12+5 = 17
common difference = 6
Sum of n terms:-
Sn = (n/2) [ 2a1 + d(n - 1)]
Sum of 30 terms:-
S30 = (30/2)[ 2*11 + 6(30-1)]
= 15 * ( 22 + 174)
= 15 * 196
= 2940 Answer
I think its 7,900 if not then you are correct
