Wesley bought 3 times as many chocolate bars as candy bars. The total mass of chocolate bars and candy bars was 985 g. The mass of candy bars was 5 g less than that of the chocolate bars. The mass of 1 candy bar was 65 g heavier than 1 chocolate bar.

1. Find the number of candy bars that Wesley bought.
2. Find the mass of 1 chocolate bar.

	Chocolate Bars	Candy Bars	Total
Number of sets	3 sets	1 set
Compare each	1 u	1 u + 65
Total value	495 g	490 g	985 g

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

Mass of candy bars = (985 - 5) ÷ 2 = 490 g
Mass of chocolate bars = 490 + 5 = 495 g

Mass of 1 set of candy bars = 490 g
Mass of 1 set of chocolate bars = 495 ÷ 3 = 165 g

Difference in the mass between 1 set of candy bars and 1 set of chocolate bars
= 490 - 165
= 325 g

Number of items in each set
= 325 ÷ 65
= 5

Number of candy bars
= 1 x 5
= 5

(b)
Mass of 1 candy bar
= 490 ÷ 5
= 98 g

Mass of 1 chocolate bar
= 98 - 65
= 33 g

Answer(s): (a) 5; (b) 33 g
