Answer:
27
Step-by-step explanation
Sally = 4 x 3 = 12(left) + 15(spent) = 27
Lucy = 24(spent) + 3(left) = 27 (we dont multiply this part bc Lucy spent 9 more dollars than Sally, 3 x 3 is 9 which equals the difference)
Answer:
Step-by-step explanation:
we know that the total time of the show is 30 minutes.
commercial part = 3x+2
entertainment part = y
also we know that y = 3x +2
y + 3x+2 = 30
we can also say that
2(3(x) +2) = 30
so then
6x +4 = 30
6x = 26
x = 4
4 is the time in minutes for commercials
Let x be the number of 15cents increase in price.
Revenue per month = (10,000 - 500x) × ($0.95 + $0.15x)
= $9500 + $1500x - $475x - $75x
= $9500 + $950x
Hope this helps! :)
