Question

An athletic director pays $90 for 12 sun visors for the softball team. how much will the athletic director pay to buy 15 more sun visors?

Answer 1

`\$112.5`

Explanation:

we know that

An athletic director pays
`\$90` for
`12` sun visors

so by proportion

Find how much pay to buy
`15` sun visors

`(90)/(12)(\$)/(sun\ visors)=(x)/(15)(\$)/(sun\ visors) \\ \\x=15*90/12\\ \\x=\$112.5`

Answer 2

An athletic director pays $90 for 12 sun visors for the softball team. The rate per sun visor is equal to $90 / 12 sun visor = $ 7.5 per sun visor. So the athletic director should pay ($ 7.5 per sun visor)*(15 sun visor) = $ 112.5
