Question

Max is getting his senior pictures taken. He has to pay $39.95 for a sitting fee and $0.49 per picture. He has $75 to spend. How do you write and solve an equation to determine how many pictures Max can buy?

Answer 1

Equation: `40.44x<=75`
Pictures Max can buy: 1

Explanation:

In this problem, `x` represents the amount of pictures Max can buy. So, `x(39.95+0.49)<=75`.
`40.44x<=75`.

`x=75/40.44`

Now, `75/40.44` approximates to 1.85, but we have to round down, so Max can buy only one picture.

We can check:

`1(40.44)<=75`.

`80.88` is greater than 75.

Therefore, Max can buy one picture.
