The price of one more-expensive blouse) . . . . . P
The cost for three of them . . . . . . . . . . . . . . . . 3 P

The price of one less-expensive blouse . . . . . P - 3
The cost for three of them . . . . . . . . . . . . . . 3(P-3) = 3P - 9

The cost for all six blouses . . . . . 3P + (3P - 9)

That's $91.50 . 3P + (3P - 9) = $91.50

3P + 3P - 9 = $91.50

Combine like terms: 6P - 9 = $91.50

Add 9 to each side: 6P = $100.50

Divide each side by 6 : P = $16.75

Each more-expensive blouse cost $16.75 .

Each less-expensive blouse cost $13.75 .

Check: 3 ($16.75) + 3 ($13.75)

= $50.25 + $41.25

= $91.50 yay !
