Question

Laura spent ⅕ of her money on a new pocketbook and had $90 remaining. How much did she spend on her new pocketbook?

Answer 1

Answer:

$18

Step-by-step explanation:

90/5

18

Answer 2

Answer:

$22.50

Step-by-step explanation

90 is 80% (4/5) of what number (x)? So you do 90 times 100 = 9000 and 80 times x is 80x and then 9000 divided by 80 is 112.5 so she had 112.5 to begin with but she spent 1/5 so 112.5 divided by 5 is 22.5 so 1 fifth is 22.5
