Question 2

$50, because the pattern is adding $5 to the regular cost of each item and $45 + $5 = $50.

$47, because the pattern is adding $2 to the regular cost of each item and $45 + $2 = $47.

$120, because the pattern is doubling the regular cost of each item and $60 × 2 = $120.

$43, because the pattern is subtracting $2 from the regular cost of each item and $45 – $2 = $43.

Question 3

90 + 70 + 64 = 224 square feet

100 + 70 + 80 = 250 square feet

100 + 70 + 64 = 234 square feet

100 + 80 + 64 = 244 square feet
