Mistu purchased a basketball hoop for her driveway from a sporting goods store. After the sales tax rate of 5.5% was applied, the total cost came to $179.35.How much money would Mistu have saved if she had used a coupon good for 10% discount?

x = orig cost without tax
0.055x = orig cost with tax
x + 0.055x = $179.35
1.055x = 179.35
x = 170.00 orig cost
170.00  170.00(0.10) = new cost with coupon without tax
170.00  17.00 = 153.00 new cost no tax
153.00 (0.055)tax = 8.42 tax
153.00 + 8.42 = 161.42 new total cost
179.35  161.42 = 17.93 savings
