Becky bought a new television and paid 8% sales tax. she had a coupon for 15% off of the original price of the television (t) before tax. in terms of t, which of the following is the final price becky paid for the television?
a. 0.08(0.15t)
b. 0.08(0.85t)
c. 1.08(0.85t)

Let's say the TV cost $100

Now if we multiply 0.08(.85(100)) we'll first get $85 which is 15 percent off.

If we choose option A then that will be wrong because you're new total would be $15 dollars instead of $85

Option B when multiplied by .08 will bring the price of the TV all the way down to $6.80 which that doesn't make sense.

Multiplying by 1.08 will be considered as tax and therefore option C is correct.

Ai just took the test
