Jacob invested $300 in a savings account and earned $81 in simple interest at the end of 9 years. what was the interest rate
Brilliant_brown [7]

Answer:

A.

Step-by-step explanation:

We use the simple interest equation of A=P(1+rt).

A-the total amount with interest earned

P-the initial amount or principal

r-rate

t-time in years

We substitute the values P=300, A=381, and t=9. We then solve for r.

381=300(1+9r)

We divide both sides by 300.

\frac{381}{300}=\frac{300(1+9r)}{300}

Simplify.

1.27=1+9r

We subtract 1 from both sides.

1.27-1=1-1+9r

Simplify.

0.27=9r

We divide by 9.

\frac{0.27}{9}=\frac{9r}{9}

r=0.03

We need to convert the decimal to a percentage by multiplying by 100.

The interest rate is 3%.

Kendrick’s bill for lunch was $24.50. He left the server an 18% tip. What is the total amount that Kendrick paid for lunch inclu
Mice21 [21]

Answer:

$28.91

Step-by-step explanation:

The first step is to calculate the amount of the tip. You multiply the price (24.50) by the tip amount (18% or 0.18). The product is 4.41. Then, you add the tip to the bill. 24.50+4.41=28.91.
