Cost for 6 snacks:
Cost for x snacks:

Answer 1

(a) $83 for 6 snacks

(b)
`y = 65 + 3x` --- for x snacks

Explanation:

Given

Let:

`n \to people`

`ticket =\$13` --- per individual

`snacks = \$3` --- per individual

Solving (a): Amount for 6 snacks

The amount paid (y) is:

`y = ticket * n + snacks * 6` ---- because she bought 6 snacks

`y = 13 * n + 3 * 6`

`y = 13n + 18`

`n = 5` ---- Annabelle and the 4 kids.

So:

`y =13*5+18`

`y =65+18`

`y =83`

Solving (b): For x snacks

The amount paid (y) is:

`y = ticket * n + snacks * x` ---- because she bought x snacks

`y = 13* 5 + 3* x`

`y = 65 + 3x`
