Answer:
2525
Step-by-step explanation:
1. Draw a block diagram to illustrate the different types of chocolate bars. (In this diagram, the creamy chocolate bars are shown as orange blocks, the milky chocolate bars as blue blocks and the white chocolate bars as red blocks.)
2. Since the number of creamy chocolate bars was 5 times the number of milky chocolate bars, we can replace one orange block (creamy) with 5 blue blocks (milky).
Since the number of white chocolate bars was 715 more than the number of milky chocolate bars, we replace one red block with one blue block + 715.
3. Looking at the block diagram, find the number of milky chocolate bars (blue block)
4250 – 715 = 3535
7 blue blocks = 3535
1 blue block = 3535 ÷ 7 = 505
The number of milky chocolate bars made was 505.
4. Calculate the number of creamy chocolate bars.
The number of creamy chocolate bars was 5 times the number of milky chocolate bars = 5 × 505 = 2525
