Mrs. bull spilled coffee on her computer during the first week of school! the total cost after tax to repair it is represented by 0.09(75ℎ) + 75ℎ , where h represents the number of hours it takes to repair her computer. what part of the expression represents the amount of tax mrs. bull has to pay? show all work & explain.

0.09(75h) is the part of the expression that represents the amount of tax Mrs.Bull has to pay. 75h (h representing the number of hours it will take to repair the laptop) is the amount before tax, so 0.09 and 75h multiplied will equal the total of tax.

I hope this helps

total stock value at initial stock price on friday/ initial stock price on friday = number of shares

3539.04/73.73 = 48 shares
