Jolie uses 1.5 tomatoes every day to prepare her salad. if x equals the number of tomatoes jolie had before she made her salad and z equals the number of tomatoes left after the salad is made, which equation represents the number of tomatoes jolie has after she made her salad? x = 1.5 − z z = 1.5 − x z = x − 1.5 x = z − 1.3

The correct answer is the third choice, z = x - 1.5

Step-by-step explanation:

x is the number of tomatoes she has before making the salad.

She uses 1.5 tomato to make a salad.

That means you need to subtract 1.5 tomatoes from the original number of tomatoes, x.

The number of tomatoes after making the salad is x - 1.5

We are told that the number of tomatoes left after making the salad is z, so z musty equal x - 1.5

z = x - 1.5

The correct answer is the third choice.

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.
