Question

Write an equation for the situation.

Answer 1

Let a be the variable for the equation.

now equation for the situation is 1a + 2(a-3) = 91.50
1a + 2a - 6 = 91.50
3a = 97.50

thus, a = 97.5/3 = 32.5$

Now, price of first blouse = 32.5
The price of other two blouse = 32.5-3 = 29.5$

Answer 2

Here is the answer:
Let x equal the price of 1 regular priced shirt
3x+(2(x-3))=91.50
