Step-by-step explanation:

The margin of error is 7%. This means the 63% could either 7% too high or 7% too low. Answer choice A is the only answer choice that is within the range of percents that it could possibly be(between 56% and 70%). Answer choice B is 10% off, 3% out of the range. Answer choice C is 25% off, 18% out of the range. Answer choice D is 32% off, 24% out of the range. Hope this helps. :)

April and Amy have a combination age oh 53.Amy is 9 years younger than April.what are April and Amy ages.
Lostsunrise [7]

If the total age of both April and Amy are 53

And Amy is 9 years younger than april.

Then to solve for Amy's age you would subtract 9 from 53 and divide by 2

which equals 22

Since amy is 9 years younger than April, then April's age is Amy's age 22 + 9 which gives you 31

April's age is 31 and Amy's age is 22
