Answers and reasoning
Reveal the teacher answer key
- (0,0), (2,3), (4,6), (6,9); 6 tickets earns $9
Scale both quantities by each batch count; plot horizontal tickets and vertical dollars.
- A $2.5/marker; B $3/marker; A is cheaper
Divide each price by its marker count; compare 2.5 with 3.
- A $1.5/marker; B $2/marker; A is cheaper
Divide each price by its marker count; compare 1.5 with 2.
- 3/20; 0.15
15% = 15/100 = 3/20; divide by 100 for 0.15.
- 8
20/100 × 40 = 8.
