Answer: 2 hours 15 minutes
Step-by-step explanation:
3/4 of an hour times 3 will be 9/4; each fourth is 15 minutes. 9 times 15 is 135 minutes, which is 2 hours and 15 minutes
First, you have to substitute for x, which would make the problem f(x)=7.45(-4.3)+33.7
Now, you just have to use the PEMDAS method (Parenthesis, Exponents, Multiplication, Division, Addition, Subtraction)
f(x)= -32.035+33.7
f(x)=1.665
Answer:
C = 0.65M+19.65
Step-by-step explanation:
Given the the standard charge S (in dollars) given by the function
S = 0.40M + 15.75, where M is the number of miles driven.
Also the insurance charge I (in dollars) is given by the function
I = 0.25M + 3.90
If C is the total charge (in dollars) for a rental that includes insurance, then:
C = S + I
Substitute the given function into the expression:
C = 0.40M + 15.75 + 0.25M + 3.90
Collect like terms
C = 0.40M+0.25M+15.75+3.90
C = 0.65M+19.65
<em>Hence an equation relating C to M is expressed as C = 0.65M+19.65</em>
