Candice bought 3 shirts. each shirt cost the same amount and was discounted by $3.66. candice paid a total of $62.31 before tax. how much did each shirt cost before the discount?

Discount per shirt=3.66

so therefor
3x=3 times original cost per shirt
discount means minus
3x-3(3.66) since 3 discounts since 1 discount per shirt

she paid 62.31
after discount so
3x-3(3.66)=62.31
solve for x which is cost per shirt orinilally

3x-3(3.66)=62.31
divde both sides by 3
x-3.66=20.77

add 3.66 to both sides
x=24.43
cost per shirt was $24.43
