Wyatt should charge $9.26 before 8% sales tax if he does not want customers to pay more than $10.00
They will actually be charged $10 exactly.
9.26*.08= .74
.74+9.26= 10
Answer:
12+3x=27
Step-by-step explanation:
Follow the words and write it as you read it, if it's (times) you multiply and if it's (larger), it's addition.
X = 0 ; y = 10 ; 10 = a(0) + b(0) + c
c = 10
x=2 ; y = 15 ; 15 = a(4) + b(2) + 10 ; 5 = 4a+2b
x=4 ; y=18 ; 18 = a(16) + b(4) + 10 ; 8 = 16a + 4b
2(5) = (4a+2b)2
-
<u> 8 = 16a + 4b
</u> 2 = -8a
a = -0.25
b = 2
y = (1/4)x^2 + 2x + 10 ; 4y = x^2 + 8x + 40
