F(x) = 3x^2 + 4x - 1
f(-3) = 3(-3)^2 + 4(-3) - 1
f(-3) = 3 * 9 - 12 - 1
f(-3) = 27 - 12 - 1
f(-3) = 15 - 1
f(-3) = 14
Answer:
the sales tax percent is therefore: 7.75%
Step-by-step explanation:
The sales tax she paid is $69.75, for a sofa whose sale price is $899.99.
Since $69.75 is the unknown (x) percent of $899.99, then we write this statement in math terms as:
69.75 = x * 899.99
solving for x we get:
x = 69.75 / 899.99
x = 0.0775
this is the decimal form of the percent, and in order to write it as percent, we multiply it by 100:
the sales tax percent is therefore: 7.75%
