1 Karl added 9. ice cubes to his ice tea. Each ice cube lowers the temperature of the tea by 2F. The tea was 76°F before he added the ice. What was the temperature after the ice was added?

its 58 degreese F

Step-by-step explanation:

start with 9*2 and that equals 18 then you subtract 18 from 76 which equals 58. that is your answer 59 degrees F

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.
