The science supply store is having a sale. all graduated cylinders are 25% off. mrs. delmar buys four graduated cylinders that were originally $8.00 each and six that were originally $9.50 each. show work
a. how much money will mrs. delmar save?
b. what percent of the original price will mrs. delmar pay?
c. suppose the sales tax is 4%. what is mrs. delmat's total cost?

Given:
Sales discount = 25%
Original price of 4 Graduated cylinder = $8
Original price of  6 graduated cylinder = $9.50

8 x 25% = 2 value of sales discount
2 x 4 = 8 sales discount on 4 cylinders.

9.50 x 25% = 2.38 value of sales discount
2.38 x 6 = 14.28 sales discount on 6 cylinders

a) 8 + 14.28 = $22.28 savings of Mrs. Delmar
b) 100% - 25% = 75% of the original price will be paid by Mrs. Delmar
c) 4 cylinders = 8 x 75% = 6 x 4 = 24
    6 cylinders = 9.50 x 75% = 7.13 x 6 = 42.78
total cost of cylinders = 24 + 42.78 = 66.78
sales tax = 66.78 x 4% = 2.67

Total payment = 66.78 + 2.67 = $69.45 Mrs. Delmar's total cost
