Responses

30+(2⋅4+5⋅2)

30 plus left parenthesis 2 times 4 plus 5 times 2 right parenthesis

(2⋅4+5⋅2)−30

left parenthesis 2 times 4 plus 5 times 2 right parenthesis minus 30

30−(2⋅4+5⋅2)

30 minus left parenthesis 2 times 4 plus 5 times 2 right parenthesis

30−(2+5)

Answer 1

30 − (2⋅4 + 5⋅2)

Explanation: total cost = 2·4 + 5·2 = 8 + 10 = 18, so money left = 30 − 18 = 12.
