Suppose that a certain basketball athlete earned $18,000,000 to play 80 games, each lasting 48 minutes. (assume no overtime games.) assuming that the athlete played every minute of every game, how much did he earn per minute? (round to the nearest dollar per minute as needed.)

$4687.50/minute

Step-by-step explanation:

First find how much the athlete earned each day.

Divide total earnings by number of games.

$18,000,000 ÷ 80 games = $225,000/game

Find out the earnings per minute.

Divide that number by the number of minutes in each game.

$225,000 ÷ 48 minutes = $4687.50/minute

Therefore the athlete earned $4687.50 per minute.

a 4/6 = 9/12   not proportional

step-by-step explanation:

to find which are not proportional, we can use cross products

if it is true, they are proportional.   if it is not true, they are not proportional.

a 4/6 = 9/12

4* 12 = 6*9

48 = 54

not this is not proportional  

b 2/3 = 12/18  

2* 18 = 3 * 12

36 = 36

this is proportional

c 5/4 = 10/8  

5*8 = 4*10

40 = 40

this is proportional

d 7/5 = 35/25

7*25 = 5 * 35

175 = 175

is proportional
