First you make an equation and establish a variable.
x=amount of hours the DJs will charge the same amount
100+21x=150+15x
Now you solve for x and that will get you your answer.
100+21x=150+15x
-21x -21x
100=150-6x
-150 -150
-50=-6x
8.3333...=x
You can round the answer to $8.33
Hope I helped.
Answer:
i got 49.470 so just round it or make it a fraction
Step-by-step explanation:
Answer:
a)$347.5
b)$0.33
c)$115.83
Step-by-step explanation:
Cost for renting per day= $9.99
Cost per mile = $0.33
Number of days rented=3
Cost for renting for 3 days= 3*$9.99=$29.97
Number of miles drive= 865
Cost per mile $0.33
Total cost =$0.33*865=$285.45
cost of gas= $32.08
a)cost of renting a sedan = $29.97 +$285.45 + $32.08 =$347.5
b)Total cost per mile = $285.45/865 = $0.33
c) $347.5/3 =$115.83
Answer:
there are 20 girls in the band
Step-by-step explanation:
let number of boys= x
let number of girls = 10+x
so
x+10+x=30
2x=30-10
2x=20
x=20/2
x=10....
so if x= 10 then number of boys=10
number of girls=10+10=20....
