I think it’s C
maybe it’s right
<u>Answer:</u>
The correct answer option is B. c = 25 + 2m.
<u>Step-by-step explanation:</u>
We are given that a movie rental club charges a one time fee of $25 to join and $2 for every movie rented.
We are to determine whether which of the given equations in the answer options represent how much you would spend to join the club and rent movies for a year.
The correct answer option is B. c = 25 + 2m.
One time charges = 25 plus $2 multiplied by the number of movies rented.
Answer:
Gabby received
7 nickels
10 dimes
3 quarters
Step-by-step explanation:
Let
x----> the number of dimes
y----> the number of nickels
z---> the number of quarters
Remember that
1 dime=$0.10
1 nickel=$0.05
1 quarter=$0.25
we know that
0.10x+0.05y+0.25z=2.10 ------> equation A
x=y+3-----> equation B
z=y-4 -----> equation C
substitute equation B and equation C in equation A and solve for y
0.10(y+3)+0.05y+0.25(y-4)=2.10
0.10y+0.30+0.05y+0.25y-1=2.10
0.40y=2.10-0.30+1
0.40y=2.80
y=7 nickels
<em>Find the value of x</em>
x=y+3 -----> x=7+3=10 dimes
<em>Find the value of z</em>
z=y-4 -----> z=7-4=3 quarters
therefore
