10 - 2.99 = 7.01 and 7.01 - 1.07 = 5.94 so you will get 5.94 in change
The expression would be 32+3x where x represents the cost of each shirt. If the shirts were $9 each max would have spent $59
Answer:

Step-by-step explanation:
To factor the equation, break it into two binomials which multiply to make the equation. To write these binomials (x+a)(x+b), find factors which multiply to -20 and add to -1 for a and b.
20: 1, 2, 4, 5, 10, 20
-5+4 = -1

It would be 20 hrs because if you put them both in an equation aka y=25x+100 and y=30x just plug in numbers into the x until they both have the answer which in this case is 20
