Two pounds of grapes cost $5 Jordan says that’s 2.5 Pounds per dollar. Emika says it’s 0.4 pounds per dollar. Which one is correct ?

2.5 pounds per dollar
0.4 pounds per dollar
Neither

Btw I need a explanation please help

0.4 per dollar

Step-by-step explanation:

to get one dollar you would need to divide 5 by 5. you would need to do the same thing to the 2 punds and divide that by 5 which would give you 0.4.

Jordan got 2.5 per dollar because she/he divided the 2 pounds by two thinking that would make 1 dollar. And they divided the 5 dollars by 2 to get 2.5 pounds which should have been dollars(if that makes sense)

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.
