Lincoln middle school plans to collect more than 2,000 cans of food in a food drive. so far, 668 cans have been collected. write an inequality to find numbers of cans the school can collect on each of the final 7 days of the drive to meet this goal. identify what your variable represnts.

Step-by-step explanation:

Given:

Lincoln middle school plans to collect more than 2,000 cans of food

They have already collected 668 cans

To Find:  WRITE AN INEQUALITY to find numbers of cans the school can collect on each of the final 7 days of the drive to meet this goal.

Solution :

Let x be the number of cans collected on each day.

Cans collected on 7 days = 7x

Since they already collected 668 cans

So they have total cans = 7x+668

We are given that they are required to collect more than 2000 cans

⇒

Thus this is the required inequality to find the numbers of cans collect on each final 7 days of drive

Now,

⇒

⇒

⇒

⇒

Thus they require to collect more than approx. 191 cans each day

the correct answer is 5 6 and 7

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.
