Zane bought 3 times as many caramel bars as candy bars. The total mass of caramel bars and candy bars was 888 g. The mass of candy bars was 24 g less than that of the caramel bars. The mass of 1 candy bar was 70 g heavier than 1 caramel bar.

1. Find the number of caramel bars that Zane bought.
2. Find the mass of 1 candy bar.

	Caramel Bars	Candy Bars	Total
Number of sets	3 sets	1 set
Compare each	1 u	1 u + 70
Total value	456 g	432 g	888 g

(a)
Mass of candy bars = 1 set
Mass of caramel bars = 3 sets

Mass of candy bars = (888 - 24) ÷ 2 = 432 g
Mass of caramel bars = 432 + 24 = 456 g

Mass of 1 set of candy bars = 432 g
Mass of 1 set of caramel bars = 456 ÷ 3 = 152 g

Difference in the mass between 1 set of candy bars and 1 set of caramel bars
= 432 - 152
= 280 g

Number of items in each set
= 280 ÷ 70
= 4

Number of caramel bars
= 3 x 4
= 12

(b)
Mass of 1 candy bar
= 432 ÷ 4
= 108 g

Answer(s): (a) 12; (b) 108 g
