Mr. Jenkins deposited $1,250 into an account. He made no additional deposits or withdrawals. Mr. Jenkins earned 4.25% annual simple interest on the money in the account. What was the balance in dollars and cents in Mr. Jenkins’s account at the end of 4 years?

Step-by-step explanation:

1250(1 + .0425*4)

 $1462.50  See below

Step-by-step explanation:

Initial deposit = $ 1,250

Interest rate = 4.25% annual simple = 0.0425

Time of investment = 4 years

simple interest formula  is :

A = P * (1 + rt), where:

A = final amount

P = initial principal balance

r = annual interest rate

t = time (in years)

A = 1,250 * (1 + 4 * 0.0425)

A = 1,250 * 1.17

A = 1,462.50

$9.41

step-by-step explanation:

answer: c, the green line

step-by-step explanation:

there is no black line, eliminate b.

simple interest implies periodic payments, but the red line shows no payments, eliminate d.

simple interest has equal payments. if paid say every day, the graph is about a straight line (actually a stairstep).

the yellow line is not straight, eliminate a.

check: the green line is straight, answer is c.

simple interest with positive interest rate gives a straight line sloping up to the right. green line:

g(t) = $100 + ($200-$100) ÷ (20 years) × (t years)

= $100 + (4%/year) × ($100)(t years)

incidentally, the yellow line curving upward represents continuously compounded interest

y = $100 × 2^(t years / (14 assuming the yellow line hits $200 at 14 years. 2^0 is 1, so y(0) = $100; 2^(14/14) is 2, so y(14) = $200.
