A t-shirt company sells t-shirts for $25 a piece if you buy less than 10 t-shirts. $20 a piece if you buy any amount between 10 and 50 t-shirts, and $15 a piece if you buy more than 50 t-shirts shipping the t-shirts is a flat fee of $3, no matter the size of the order. Part A: write write a piecewise-defined function that represents the total price for ordering t-shirts.

it should be101 dollars ;)

step-by-step explanation:

step 1: simplify both sides of the equation.

7x+8(x+

)=3(6x−9)−8

7x+(8)(x)+(8)(

)=(3)(6x)+(3)(−9)+−8(distribute)

7x+8x+2=18x+−27+−8

(7x+8x)+(2)=(18x)+(−27+−8)(combine like terms)

15x+2=18x+−35

15x+2=18x−35

tep 2: subtract 18x from both sides.

15x+2−18x=18x−35−18x

−3x+2=−35

step 3: subtract 2 from both sides.

−3x+2−2=−35−2

−3x=−37

step 4: divide both sides by -3.
