A(h)=4h+70, A(h)=dollars to rent for h hours, h=hours rented.
B(h)=5h+60, same variable explanations...
....
To compare the two values at 6 hours you have:
A(6)=4(6)+70=24+70=$94
B(6)=5(6)+60=30+60=$90
So at 6 hours Company B would charge $4 less than Company A
...
Savings at 7 hours of rental by using B instead of A is:
S(h)=A(h)-B(h)
S(h)=4h+70-5h-60
S(h)=-h+10
S(7)=-7+10=$3
So at 7 hours, Company B saves you $3.
I honestly do not know this seems to me to be a trick question
Answer:
d = 13 and n = 52
Step-by-step explanation:
Number of dimes: d
Number of nickels: n
Then d + n = 65, and n = 4d
Substituting 4d for n in the first equation, we get:
d + 4d = 65, or 5d = 65. Then d = 13 and n = 52
