Given:
Credit card balance : 650
APR: 19.85%
Minimum payment : 20
I used an online Credit card calculator to solve for the total amount that Jose will pay for his purchase and how long it would take him to pay it.
It would take Jose 4 years to pay off his stereo.
4 years x 12 mos/yr = 48 months
48 mos x 20 min. pyt = 960 total amount paid.
960 - 650 = 310.
Had Jose opted to pay in cash, he would have been able to save 310.
So Regina has 120 coins=total
120=total
we will use q=number of quarters and d=number of dimes
120=d+q
she has 10 more dimes than quarters
d=q+10
so if we susitute this into the equation then we get
120=(q+10)+q
add like terms
120=2q+10
subtract 10 from both sides
110=2q
divide both sides by 2
55=q
she has 55 quarters
subtitute into second equation
d=10+55
d=65
dimes=65
quarters=55
Answer:
(4,-9)
Step-by-step explanation:
Answer:
x=-4, y=8/3. (-4, 8/3).
Step-by-step explanation:
4x-9(-2/3x)=-40
4x+18/3x=-40
4x+6x=-40
10x=-40
x=-40/10
x=-4
y=-2/3(-4)
y=8/3
