Remember you can do ANTYTHING to an equaton as long as you do it to both sides

remember distributive property
a(b-c)=ab-ac

so
first distribute the 8 to theh (q-11)
8(q-11)=8q-88

now we have
20+8q-88=-12
8q-68=-12
add 68 to both sides
8q+68-68=68-12
8q+0=56
8q=56
divide both sides by 8
8q/8=56/8
1q=7
q=7

You distribute the 8 into q and -11 and you get 20+ 8q-88= -12. Now combine like terms -88 +20 or 88-20 and you get 8q - 68 = -12. Add 68 to both sides of the equal sign. You get 8q =56. Divide 8q by 8 and 56 by 8 to get q by itself. Finally your answer is q=7

1. Taylor needs to purchase a car. The car Taylor plans to purchase costs $10,000. Taylor has saved $2,000 to use as a down paym
Alexxandr [17]

Answer:

a. The amount Taylor will need to finance is $8,000

b. The amount Taylor pays as interest in one year is $400

Step-by-step explanation:

The given parameters of the financing for the car are;

The cost of the car Taylor plans to purchase, C = $10,000

The amount Taylor has saved to be used as down payment, S = $2,000

The interest rate of the credit Taylor is offered = 5%

The duration given for repayment of the loan = 5 years

a. To purchase the car, the amount Taylor will need to finance, 'P', is given as follows;

P = C - S

∴ P = $10,000 - $2,000 = $8,000

b. The amount of interest on the loan in one year, 'I', is given by the following formula;

I = \dfrac{P \times R \times T}{100}

Where;

I = The interest payed

P = The principal amount taken as loan = $8,000

R = The interest rate = 5% APR

T = The time period the interest is applied = 1 year

Plugging in the values, we get;

I = \dfrac{\$ \, 8,000 \times 5 \times 1}{100} = \$ \, 400

The interest Taylor will pay on the loan in one year, I = $4,00
