Your cell phone has 983.5 MB of free space. You save a 14-MB picture and download two song that are the same size Your cell phone now has 9749 MB of free space What is the size of ead
song?

 36 MB

Step-by-step explanation:

  let size of 1 song  =  x

∴ size of two songs = 2x

∴  9835 - 14 - 2x  =  9749

               2x  =  72

            ∴   x  =  36 MB

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.

i think the amount would be $140.62
