Answer:
d thx for points
Step-by-step explanation:
No, the correct answer is 23.75. Try plugging it into a calculator.
Just subtract the 1st equation from the 2nd, as follows:
<span> 3x+6y=33
-(</span>3x+4y=19)
-----------------
2y= 14, and y = 7. Sub 7 for y in either of the original equations to obtain the value of x. Write your answer in the form (x, 7).
<span>If each shirt costs $10 within the purchase of 1 to 75 shirts, the function will be: 10x (with x being the number of shirts, from 1 to 75). If each shirt costs $7.50 within the purchase of 76 to 150 shirts, the function will be: 7.5x (with x being between 76 and 150). Finally, if each shirt costs $6 within the purchase of 150 or more shirts, the function will be: 6x (with x being any number from 150 up). </span>
