Danielle is saving to buy a flat screen television that cost $510. she wants to know how long it will take to save the money and writes the expression 510 ÷ [(35×11)]. will daniels expression her find how long it will take to save the money she needs? explain your answer.

$510 is the amount she needs.

35*11 can reffer to a lot of things, let's suppose that she saves wins $35 and works 11 hours per day, so the amount would be equal to the amount of money that she wins per day.

Then the calculation

510/(35*11) would be equal to the amount of days that she needs to work to save the exact amount of 510 dollars, then this equation can help her.

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.
