<h3>How to calculate the number of custome?</h3>
From the information, the number of costumes she can alter varies directly with the amount of time spent working.
Since Belinda can alter four costumes in one hour, let the number of costumes she can alter in four and a half hours be represented by x.
This will be:
1/4 = 4.5/x
Cross multiply
x = 4.5 × 4.

Answer:
7 red shirts
6 green shirts
11 blue shirts
4 yellow shirts
Step-by-step explanation:
Let y represent the number of green shirts.
So y+5 is the number of blue shirts.
And y-2 is the number of yellow shirts.
And we have 5 red shirts.
Therefore,
7+5+y+y-2+y=28
12-2+3y=28
10+3y=28
3y=28-10
3y=18,divde through by 3
y=6
