Answer: Total amount earned by Laney in 4hour=$138
Total amount earned by Maka in 4hours=$134
Difference =$4
Step-by-step explanation:
Since
Maka charges can be modeled by the equation F=30h+14,
where h =number of hours that Maka tutors
F = the total amount earned. Following same model
With 14 being the charge in dollar for travel expenses.
Laney charging $10 for travel expenses plus $32 per hour of tutoring can also be represented as
F= 32h +10
Such that total amount earned by
Maka in 4hours gives
F=30h+14
F=30x4 +14
F=120+14=$134
In the same vein the total amount earned by Laney in 4hours gives
F=32h+10
F= 32x4+10
F=128+10=$138
The difference in money earned by Laney and Maka = $138-$134= $4
Answer:
Step-by-step explanation:
A value that is 9.75 less than p can be represented by the expression ...
p - 9.75
We are told that value is equal to 64, so the equation is ...
64 = p - 9.75
__
This equation is solved by adding 9.75 to both sides.
64 +9.75 = p -9.75 +9.75
73.75 = p
The store price is $73.75.
I believe the answer is 7x-y
