Answer 4

(450 + 348) x 7

Answer 5

$10 + (4 x $8)

Answer 6

To find the total cost of the paint brushes, we can multiply the cost per brush by the number of brushes:

3 x $2.25 = $6.75

To find the total cost before the coupon, we can add the cost of the paint box and the brushes:

$15.35 + $6.75 = $22.10

After the coupon is applied, the total cost becomes:

$22.10 - $2.00 = $20.10

To find the amount each person paid, we can divide the total cost by the number of people:

$20.10 ÷ 3 = $6.70

Therefore, the expression that represents the amount each person paid is $20.10 ÷ 3 or $\boxed{\frac{20.10}{3}}$.

Answer 7

(12 + 6) × (11 - 7) = 72
