On Friday. 280 Fry Middle Schodl students purchase pizza in the cafeteria. Thirty-nine percent purchased pepperoni pizza, 26% purchased hamburger pizza, and the rest purchased cheese pizza. How many students bought cheese pizza?

98 students purchased cheese pizza.

Step-by-step explanation:

Subtract 39% from 280, then subtract the other 26% from 280. Your answers should be 109.2 and 72.8. Subtract 109.2 from 280 to get 170.8, then subtract 72.8 to get 98. There's your answer, hope this helped!

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.
