Answer 1

4

Explanation:

If sandwiches are 6 dollars each, then chips are 3 dollars, she only bought 5 sandwiches for 6 each for 30 dollars(5*6=30).So, she has 12 dollars left to spend since she spent 42 dollars. And 4 *3=12so she only bought 4 bags of chips.

Answer 2

She bought 3 bags of chips .

Explanation:

Cost of 1 sandwich = $6

We are given that Each sandwich cost three times as much as bag of chips

So, Cost of a bag of chips =
`(6)/(3)=2`

Let x be the no. of bags of chips she bought

Now we are given that She bought 5 sandwiches for 6 dollars each and spent 42 dollars.

Cost of 6 sandwiches =
`6 * 6 = 36`

Cost of x bags of chips = 2x

ATQ

`36+2x=42`

`2x=6`

`x=3`

Hence she bought 3 bags of chips .
