Mia spent 30 minutes answering the math questions on the exam. this was 1/4 of the total amount of time allotted for this section of the exam. to determine the total amount of time allotted for this section of the exam, mia set up and solved the equation as shown below.
x = 18
which best describes the error that mia made?
a. mia did not use the correct equation to model the given information.
b. mia should have multiplied both sides of the equation by 3.
c. the product of is not equal to 18.
d. the product of and should have been the value of x.

actual answer is B

Step-by-step explanation:

just took the test it is not A C or D

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.

your question is incomplete, write all the numbers in the sequence that it tells you.
