Johnny read an entire series of books with a total of 3,982 pages. in the equation below, d is the number of days it took johnny to read the book series. 3,982 = 22d what is the unit rate in the equation? a. 3,982 pages per day b. 181 pages per day c. 3,960 pages per day d. 22 pages per day

D. 22 pages per day.

Step-by-step explanation:

A is not the rate it is the amount of pages that he has to read.

B is the number of days it will take for him to finish reading all 3,982 pages.

C is literally a random number it has nothing to do with the question.

D shows the rate or number of pages he will read in d number of days.

"a" determine whether sage found the correct quotient. show your work

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.
