Raymond developed an app for smartphones. During the first week, he had 7,040 downloads from girls and 3 times as many downloads

myrzilka [38]

Answer:

The correct calculation is D. 7,040 × 3, then 21,120 ÷ 8

Step-by-step explanation:

1. Let's review the information provided to us to answer the question correctly:

Number of downloads from girls = 7,040

Number of downloads from boys = 3 times as many

Number of boys who downloaded and paid the full version = 1 out of 8

2. Which calculation yields the number of boys who bought the full version of the app?

Number of downloads from boys = 3 * 7,040

Number of downloads from boys = 21,120

Number of boys who downloaded and paid the full version = 21,120/8 = 2,640

The correct calculation is D. 7,040 × 3, then 21,120 ÷ 8
