Original price of a comic book $3.00 discount 10%

$2.70

Step-by-step explanation:

To calculate this you could use 2 ways.

1) The first method is to use the multiplier method.

To Calculate this you would multiply 3 by 0.9. This is because you are reducing the amount by 10%.

    1)Multiply $3.00 by 0.90.

2) The second method is to first find 10% and then minus that from $3.

The formula to calculate the percentage is to divide the percentage by 100 and multiplying it by the number.

     1) Divide 10 by 100.

     2) Multiply 0.1 by 3.

     3) Minus 0.3 from 3.

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.
