The at& t phone company charges $.15 per minute for long distance calls. sprint phone company totals your phone usage of each month and round the number of minutes up to the nearest 15 minutes and then charges $7.90 per hour of phone usage dividing discharge into 15 minute segments. you make five hours and three minutes worth of long distance calls this month while using the company with the lower price, how much will these calls cost?

the answer is d

the answer is in the first quadrant, which make the y-int positive.

since the dots are going down, therefore the correlation is negative

i hope it is right.

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.

(0.2)+(-8)=0.3+-3+0.3m is the equation i guess? ?

answer: group b.
