Question 3

A professional football team plays a 16 game season with a goal of averaging 44,000 per week in ticket sales. If the team averages 40,000 through the first five weeks of the year, how many will it need to average the rest of the year to come the closest to its target?

Accepted Answer

46,000</label></li>

Answer

40,000*5 weeks of the year=200,000
Pick a number and start high since there is a lot of ground to make up to get to 44,000.
46,000*11 remaining weeks of the year=506,000
Add 506000+200000=706000.
Divide this by 16. 44,125 is the answer, and since that's the closest you'll get to the target, Answer 1 is the correct choice.

Question 5

>What number (x) divided by four is equal to that same number minus 30?

Accepted Answer

Answer

x/4=x-30
CROSS-MULTIPLY. x=4(x-30)
MULTIPLY. x=4x-120
ADD -4x -3x=-120
DIVIDE -3 x=40
Answer 2.
