The bar graph shows the number of wafer flavours sold at a shop in a day.
- What percentage of the wafers sold was cherry wafers? Give your answer correct to 1 decimal place.
- The cost of each wafer was the same. The amount of money collected for blueberry wafers was $20 less than the amount of money collected for chocolate chip wafers. What was the total amount of money collected from the sale of all the wafers?
(a)
Total number of wafers sold
= 60 + 55 + 35 + 65
= 215
Percentage of the wafers sold that was chocolate chip wafers
=
Cherry wafersTotal wafers x 100
=
35215 x 100
≈ 16.3%
(b)
Number of less blueberry wafers than chocolate chip wafers
= 65 - 55
= 10
Cost of each wafer
= 20 ÷ 10
= $2
Total amount collected from the sale of all the wafers
= 215 x 2
= $430
Answer(s): (a) 16.3%; (b) $430
