Question

At most, Kyle can spend $50 on sandwiches and chips for a picnic. He already bought chips for $6 and will buy sandwiches that cost $4.50 each. Write and solve an inequality to determine how many sandwiches he can buy.

Answer 1

he can buy around nine sandwiches and he will have change

Explanation:

50-6= 44

44/4.50= 9.77

to check answer

9 x 4.50= 40.5

he can buy 9 sandwiches

Answer 2

An inequality to determine how many sandwiches he can buy is
`4.50x+6\leq 50` and no. of sandwiches he bought is 9 .

Explanation:

Let x be the no. of sandwiches he can buy

Cost of 1 sandwich = $4.50

Cost of x sandwiches = 4.50x

He already bought chips for $6

At most, Kyle can spend $50 on sandwiches and chips for a picnic.

So,
`4.50x+6\leq 50`

`4.50x \leq 50-6`

`4.50x \leq 44`

`x \leq (44)/(4.50)`

`x \leq 9.78`

Hence an inequality to determine how many sandwiches he can buy is
`4.50x+6\leq 50` and no. of sandwiches he bought is 9 .
