suppose you purchase 3 shirts and a hat. the hat cost 19.75 and you spend 56.50 in all how much does each shirt cost?

Each shirt of the same type cost: (56.50-19.75)/3 = 12.25

Suppose you purchase 3 shirts and a hat.

The hat costs 19.75 and you spend 56.50 in all.

Each shirt costs 12.25.

-

3 s + 19•75 = 56•50

3s = 36•75

s = 12•25

Each shirt will cost 12•25

56.50 - 19.75 = 36.75 (the amount you paid less the price of the hat)

The three shirts cost 36.75.

Assuming they all cost the same, each one will be:

1/3 x 36.75 = 12.25

x = shirts, y = hat

3x + y = 56.50  .... this is your equation

3x + 19.75 = 56.50

subtract 19.75 from both sides

3x = 36.75

divide both sides by 3

x = 12.25

each shirt costs $12.25

[ 56.5 - 19.75 ] / 3 dollars for each shirt

(56.50-19.75)/3=12.25. This assumes all the other shirts were the same brand and style.

Total cost of the three shirts is:

56.50-19.75

AVERAGE price of the three shirts is:

(56.50-19.75)/3

There is no way to know what EACH shirt costs.

,,, 12.25 per shirt dude
