Question

Jess saved $500 working during the summer. He plans to buy school clothes with his money. He found jea

exactly twice as many shirts as jeans, how many pairs of jeans can Jess buy without exceeding $500?

Answer 1

7

Explanation:

30( 7 ) + 14( 12 ) =448
`\leq` 500

Answer 2

167 pairs

Explanation:

Represent jeans with J and shirts with S

`S = 2J`

`Amount = \$500` --- Maximum

Required

Determine the number of pair of jeans he can buy

To represent as an inequality, we have:

`S + J \leq Amount`

`S + J \leq 500`

Substitute 2J for S

`2J + J \leq 500`

`3J \leq 500`

Divide through by 3

`J \leq 500/3`

`J \leq 167`

Hence, without exceeding $500, Jess can buy 167 pairs of jeans
