Question

Ramya paid 12.50 for a shirt and cap. The shirt was 4 times the cost of the cap. How much was the cap?

Answer 1

\[12.5=s+c\]\[s=4c\]\[12.5=4c+c\]\[12.5=5c\]\[c=2.5\]

Answer 2

Solve the following for s and c.
{s + c = 12.5, s = 4 c}
s=10, c=2.5

Answer 3

x=cost of cap
so:
4x=cost of shirt
so cost of cap and shirt equals price paid or:
x+4x=$12.50
5x=$12.50
x=$2.50
so cap is $2.50
and shirt is 4 times that amount
or4($2.50)=$10
