2. helder_edwin Group Title

$P=10.03\cdot x-77$

3. hiralpatel121 Group Title

How do we get the answer though? I want to show all the steps.

4. helder_edwin Group Title

if x is the numbers of cars serviced and u charge 10.03 per car then your revenue is x times 10.03

5. hiralpatel121 Group Title

Okay. Do you know how to do part b?

6. helder_edwin Group Title

your costs are 77 (fixed) then the profit is what i posted first

7. hiralpatel121 Group Title

And?

8. helder_edwin Group Title

for part b: $3022=10.03\cdot x-77$

9. hiralpatel121 Group Title

Then would you subtract 10.03-77 and divide the answer*x by 3022 to solve for x?

10. helder_edwin Group Title

first add 77 to both sides then divide by 10.03

11. hiralpatel121 Group Title

Okay, and whatever I get after is the answer?

12. helder_edwin Group Title

yes

13. helder_edwin Group Title

what do u get??

14. hiralpatel121 Group Title

And how would I write the answer in sentence form?

15. helder_edwin Group Title

what do u mean??

16. helder_edwin Group Title

like in school???

17. helder_edwin Group Title

i don't know. maybe "if your costs are $77 and u charge$10.03 per car serviced, then in order to make a profit of \$3022 u have to have serviced around 309 cars"

18. helder_edwin Group Title
