Answer:

22.4 quarters left

Step-by-step explanation:

40% can be written as 0.4

40% of your 20 quarters can be found by 0.4 x 20 = 8

add 8 to your 20 original quarters

20 + 8 = 28 quarters

once you go shopping you must find 20% of 28

20% can be written as 0.2

0.2 x 28 = 5.6

subtract 5.6 from 28 to get 28 - 5.6 = 22.4 quarters

hope this helps!
