Answer:
Step-by-step explanation:
<u>Given</u>
- Time = 20 years = 240 months
- Mortgage amount = $90000
- Selling price = $110000
- Monthly payment = $898.20
<u>a) total amount</u>
- 110000 - 90000 + 240*898.20 =
- 20000 + 215568 =
- $235568
<u>b) Interest cost</u>
- $235568 - $110000 =
- $125568
SOLUTION
The total cost of the books is $8
Calculating 20% off gives
Therefore the amount paid is $6.40
Answer:
d)0 and 7 are solutions of the original equation.
Step-by-step explanation:
Let's solve your equation step-by-step.
w=√7w
Step 1: Flip the equation.
√7w=w
Step 2: Solve Square Root.
√7w=w
7w=w2(Square both sides)
7w=w2
7w−w2=w2−w2(Subtract w^2 from both sides)
−w2+7w=0
w(−w+7)=0(Factor left side of equation)
w=0 or −w+7=0(Set factors equal to 0)
w=0 or w=7
Check answers. (Plug them in to make sure they work.)
w=0(Works in original equation)
w=7(Works in original equation)
