Acase of 24 pairs of the same kind of sport shoes cost a little more than 800 explain whether 28 per pair with tax included a good estimate of the price

  not particularly good, but within an order of magnitude

Step-by-step explanation:

Cost per pair is 800/24 = 100/3 ≈ 33. So 28 is off by more than 5, about 16% of the actual value.

For some purposes, an estimate within 16% would be "good." For other purposes, not so good. In many engineering applications, an estimate within 10% is "good enough." In retail applications where profit margins are less than 5%, an estimate that is off by 16% can make the difference between profit and loss.

The estimate is not particularly good, but may be adequate.

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.
