Maria completed 3/4 of her workday. create a model that represents what percent of the workday maria has worked.
a. what percent of her workday does she have left?
b. how does your model prove that your answer is correct?

Step-by-step explanation:

a) She has left 25% of her work. 1/4 is 25%.

b) In the model you can see that the total work is divided in 4 equal portions. Each portion represents 1/4 of the workday.

In the second figure you can see in green marked the portions of workday worked, as it is 3/4 it means 3 portions of a total of 4. So, one portion is left, that is marked in yellow color. One portion of a total of 4 portions, it means 1/4.

To express 1/4 in percentage, you need to divide 1 by 4 and the multiply by 100.

The percent of workday left is 25%

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.
