Question

Henry’s mom gave him $20 for his weekly allowance. Henry wants to buy a new comic book that costs $8. What percentage of Henry’s weekly allowance will he spend on the comic book

Answer 1

40%

Explanation:

Henry has a total of $20 for his allowance which is equivalent to 100%

The easiest way to then find out the percentage is moving the decimal over one place from 20. to 2.0 to find 10% which we just found out is $2, next to get up to 8, this gets multiplied by 4 and so does the 10% to get a total of 40%
