Answer:
There are 18 hats and 72 t-shirts.
Explanation:
Let t = number of t-shirts and h = number of hats.
There are four times the number of t-Shirts than hats so hats times four equal the number of t-shirts:
t = 4h
There are 54 more t-shirts than hats:
t = h + 54
You can set the equations equal to each other and solve for t:
4h = h + 54
3h = 54
h = 18, the number of hats.
By substitution:
t = 4h
t = 4(18) = 72, the number of t-shirts.
Proof #1:
t = h + 54
72 = 18 + 54
72 = 72
And Proof #2:
t = 4h = 4(18) = 72
Hope this helps! Have an Awesome Day!! :-)
