Answer:
Shorts: 38
T-Shirts: 152
Step-by-Step
The number of shorts sold can be written as (s) and the number of t-shirts sold can be written as (t)
We know that shirts are $2, and shorts are $4, and the total sales were $456, so the following equation can help us to find the answer, since if we add up the money from shirts and the money from shorts we’ll get the total sales.
4s + 2t = 456
Next, we know that shirts were bought 4 times more than shorts, so we can also write the following equation:
4s = t
Now, since we have a defined “value” for t
(t = 4s), we can substitute this value into the first equation.
4s+ 2(4s) = 456,
4s + 8s = 456,
12s = 456
s = 38
Now we can use this value in the second equation, and solve for t
4s = t
4(38) = t
152 = t
