Answer:
Let x = # of commercials
y = # of movies
<u>System of Equations:</u>
x + y = 90
40x + 110y = 500
Step-by-step explanation:
We have to set our variables before we start solving. After setting the variables, we can set up the equations. If x = # of commercials and y = # of movies, then we can assume x + y = 90, as there have been a total of 90 commercials and movies played altogether. Then, we know that their worth is $500, so the price of all the commercials played and the price of all the movies played (which is 40x + 110y) sum to $500.
Answer:
8x+$0.75x.
Step-by-step explanation:
8x is the hours you babysit and $0.75x the miles you drive.
C = 22d is the correct answer because for every day the cost increases by 22 so two days mean the cost is equal to 22 (2)
