Answer:
-30%
Step-by-step explanation:
currently, the perimeter is: 4 + 6 + 4 + 6 = 20 in.
when the width of 4 in is decreased by 3 in, the new width become (4-3) in = 1 in
therefore, the new perimeter is: 1 + 6 + 1 + 6 = 14 in
the change in perimeter is: 20 in - 14 in = 6 in
now, the percent of change in perimeter will be:
%
BUT because this change is a DECREASE, you have to put a NEGATIVE sign before the value to inducate that it's a decrease, so
change in perimeter = -30%

Answer:
C= 22.65 + 0.65M
Step-by-step explanation:
The question isn't complete without values. Assuming the following is the complete question: A car rental company's standard charge includes an initial fee plus an additional fee for each mile driven. The standard charge S (in dollars) is given by the function S=16.95+0.40M, where M is the number of miles driven.
The company also offers an insurance option to insure the car against damage. The insurance charge (in dollars) is given by the function I=5.70+0.25M.
Let C be the total charge in dollars for a rental that includes insurance. Write an equation relating C to M. Simplify your answer as much as possible
SOLUTION
Solving the question based on the above complete question:
Standard charge = S = 16.95 + 0.40M
M= number of miles
Insurance charge = I = 5.70 + 0.25M
C = total charge in dollars
Relationship between C and M:
Total charge = standard charge + insurance charge
C = S + I
C = (16.95+ 0.40M)+ (5.70 + 0.25M)
C= 16.95+ 5.7 + 0.40M + 0.25M
Collect like terms by adding together
C= 22.65 + 0.65M
