Ezra and tara sold at least 150 coupon books. ezra sold at most 30 books more than twice the number tavares sold. show and describe all possible combinations of the numbers of coupon books ezra and tavares sold. list teo possible combinations.

The answers are (110,40), (120,45), (130,50), etc.

Step-by-step explanation: Given that Ezra and Tara sold at least 150 coupon books and Ezra sold at most 30 books more than twice the number Tavares sold. We are to list the possible combinations of the numbers of coupon books Ezra and Tavares sold.

Let, 'x' and 'y' be the number of coupon books sold by Ezra and Tavares respectively. Then according to the question, we have

Writing these inequalities as equations, we have

Multiplying the first equation by 2 and adding to the second equation, we have

So,

Thus, the possible combinations are

(110,40), (120,45), (130,50),etc.

i dont know if you cant find a way its best to actually add all of them start from 105 tho

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.
