Answer Key: Exit Ticket

Proportions

k = 6 / 3 = 2; 2 × 2 = 4 cups
$6 ÷ 4 = $1.50 each; 10 × $1.50 = $15
No. 2 → 5 and 4 → 10 have the ratio 2.5, but 6 → 16 would need to be 15. The ratios aren't all equal.

Quick read: 5 cups on #1 means the student added 3 (the additive mistake). Assign Level 1 in Practice mode, where the pop-up shows why every amount must be multiplied.
