tommy owns 450 stamps, which one-fourth of the amount that henry owns. how many does henry own?

If 450 is 1/4 of the amount that Henry has, you can find Henry’s amount by multiplying 450 • 4 which gives you an answer of 1800

Or, if you’re looking for a more complicated way, which I doubt, you can set up the problem as:

1/4x=450 and solve by dividing 450 by 1/4

answer: $34.31

step-by-step explanation:

$11.99 x 3 = $35.97

$35.97 - 10% = $32.37

$32.37 + 6% = $34.31
