Tara is shopping at a department store in the mall. Before checking out she wants to make sure she brought enough money to pay for the entire purchase. If the tax rate is 7%, what is a reasonable estimate of the amount of money that Tara can expect to pay?
appr sum = 50 + 20 + 70 + 70 + 20 = 230
7% of that is ....
7% of 230 in my head is (thinking 7*23 = 141) about $14,
so my cost is appr $244, I better have about $250
(actual answer: 248.24)
