On thursday, a local hamburger shop sold a combined total of 255 hamburgers and cheeseburgers. the number of cheeseburgers sold was two times the number of hamburgers sold. how many hamburgers were sold on tuesday?

The number of hamburgers were sold on Thursday is 85

Step-by-step explanation:

∵ The number of hamburgers is x

∴ the number of cheeseburgers is 2x

∴ x + 2x = 255

∴ 3x = 255

∴ x = 255 ÷ 3 = 85

∴ The number of hamburgers were sold on Thursday is 85

22 dimes and 9 nickels

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.
