Christopher is a graphic designer who creates business websites. it takes him 2.4 hours to complete one website page. he finds out about a new software program that will cut his time in half for completing one page, but it will take him 15 hours to learn the new program.
which equation can be used to find the number of website pages, x, that christopher needs to create so that his time spent using the new program will be the same as his current time?

how many website pages would christopher need to create in order to save time using the new software program?

2.4x = 1.2x + 15

13

Step-by-step explanation:

just did it

it would take 7/10 of an hour too fill the pool.

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.
