Nikos finds a toy train set on sale for 20% off at a toy store. the original price was $35. Nikos must also pay 6.5% sales tax. What is the total amount nikos must pay for the train set?

Work:

$35 (.8) = $28

$28 (1.065) = $29.82

Explanation:

The first step is to find out how much the train set cost on sale. Since it was 20% off that would mean that it is 80% of the original price. That's why in the first step I multiplied $35 by. 8. The second step is to multiply the discounted price by the tax,.065, but since I would have to add the tax to the discounted price anyway I just made it all one equation by multiplying by 1.065 instead.

35-20% = 28

28+6,5% = 29.82
