Answer:
[tex]\boxed{C=0.35M+8.35}[/tex]Explanation:
Step 1. The expression of the charge E for renting an economy car is:
[tex]E=10.95+0.80M[/tex]And the expression of the charge L to rent a luxury car is:
[tex]L=19.30+1.15M[/tex]Step 2. Let C be the difference between renting a Luxury car and renting an economy car --> C is how much more it costs to rent a luxury car than an economy car.
We represent C in terms of E and L as follows:
[tex]C=L-E[/tex]Step 3. Substitute the known expressions for L and E into the previous equation:
[tex]C=19.30+1.15M-(10.95+0.80M)[/tex]Step 4. Simplify:
[tex]C=19.30+1.15M-10.95-0.80M[/tex]Step 5. Combine the like terms.
We combine the terms that contain M and the independent terms:
[tex]\boxed{C=0.35M+8.35}[/tex]Answer:
[tex]\boxed{C=0.35M+8.35}[/tex]
