Ricardo borrows $1,850 for 10 months at an interest rate of 12.25%. What amount will
he have paid back at the end of the loan period?

Answers

9514 1404 393

Answer:

$2038.85

Step-by-step explanation:

The value of the loan at that point is given by ...

A = P(1 +rt) . . . . . Principal P, rate r, time t (years)

A = $1850(1 + 0.1225·(10/12)) = $2038.85

Ricardo will have paid back $2038.85 at the end of the loan period.

_____

Additional comment

We assume that the loan accrues simple interest and that the amount due is the sum of principal and interest at the end of the loan period.

The question is not specific as to whether interest compounds, or whether intermediate (monthly) payments are made. There are many possible ways the loan could be repaid, generally involving different amounts for the different terms.

The ratio of collectible coins Juanita owns to coins that Elia owns is 3:1. Elia has 32 coins. How will the ratio of Juanita’s coins to Elia’s coins change if they both sell one fourth of their coins? Explain.

Answers

Hi there Maebe, since the ratio is 3:1 your answer is 96.

The ratio 3:1 is just saying Juanita has 3 times whatever Elita has. So, Elita’s 32 times 3 equals 96. :) I hope I’ve helped you. Please give me feedback if you need more help understanding!

Ajoba and Prav drive to work. Ajoba drives 45 miles in 2.5 hours. Prav drives 74 km in 1 hour 15 min. Work out the difference between their average speeds in km/h. 1 mile = 1.6 km

Answers

Answer:

30.4 km/h

Step-by-step explanation:

Ajoba: 45 miles = 72 km ; 2.5 hours

Prav: 74 km ; 1 hour 15 min = [tex]\frac{5}{4}[/tex] hours

Ajoba's average speed: 72 ÷ 2.5 = 28.8 km/h

Prav's average speed: 74 ÷ [tex]\frac{5}{4}[/tex] = 59.2 km/h

Difference: 59.2 - 28.8 = 30.4 km/h
