Simplify 5x-3-7 to -2x-3
-2x-3=15-x
Add 2x on both sides
−3=15−x+2x
Simplify 15-x+2x to 15+x
−3=15+x
Subtract 15 on both sides
-3-15=x
Simplify -3-15 to -18
-18=x
X=-18

Answer:
The correct answer is option C.$35.70
Answer:
C(x)= 41x + 680
Step-by-step explanation:
If the fixed cost is 680, that will apply regardless of how many jackets the company makes for you. The number of jackets is unknown. However, we know that the cost of producing a single jacket is 41, so we can represent that expression as 41x. Putting those things together gives us a function of the cost:
C(x) = 41x + 680
