x ----> the number of quarter coins Karen has

y ----> the number of dimes coins Karen has

Remember that

we know that

Equation that represent the amount of coins Karen has

isolate the variable y

----> equation A

Equation that represent the value of coins Karen has

----> equation B

Solve the system of equations by substitution

substitute equation A in equation B

solve for x

Find the value of y

---->

therefore

Karen has 6 quarters and 2 dimes

from the figure we get,

the x axis shows   the months and,

the y-axis shows the number of satisfied customer.

each line or each cell in upward direction (y-axis) shows 500.

the appropriate scale for the y - axis is: -

a = 2000 customers

b = 4000 customers

c = 6000 customers

d = 8000 customers

e = 10000 customers

f = 12000 customers

g = 14000 customers
