sara is looking to purchase a washer and dryer. The saturday newspaper has an advertisement for a local appliance store offering 90 days, same as cash financing. sara asked how the financing worked and learned that she could pay for the washer and dryer any time during the first 90 days for the purchase price plus sales tax. if she waited longer, she would have to pay the purchase price, plus sales taxes, plus 26.4% annual simple interest for the first 90 days. plus 3% simple interest per month on the unpaid balance after 90 days. together the washer and dryer cost 599 plus the 6.25% sales tax. Sara knew that her tax refund from the irs would be $800, so she bought the washer and dryer confident that she could pay off the balance within the 90 days. If Sara pays off the balance within 90 days, how much will she pay

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.

p = 6s

step-by-step explanation:

step-by-step explanation:

given that ab is divided into equal parts as

ac, cd, de, ef, fg, gh, hi, ib.

from this we find that f is the midpoint of ab.

so using mid point formula we find

f = (3,7)

similarly considering fb, we get

h = mid point of fb = ((6,6) and g, mid point of fh is

g = (9/2, 13/2)

i is mid point of hb

so i =(15/2,11/2)
