Ralph jordan recently bought a new lawnmower for 228.00. if he had to pay 6% sales tax on the lawnmower, what wasthe total cost of the lawnmower?
a: $251.62
b: 234.00
c: 241.68
d: 312.42

First we find what 6% of 228.00 is.

To do that we would multiply the number by the percent
So 228 x 6 = 1368
Then divide the answer by 100.
1368/100 = 13.68

You can round if you would like but in this case I believe we should leave it alone.

Which means the price was 228.00 and the tax was 13.68 we just have to add them together to find the answer.

228.00 + 13.68 = 241.68

The answer would be C.

Do you need with the x value for the minimum? its always between the two intercepts for a parabola
