Huixian needs 171 pens , 63 pencils and 27 erasers into identical gift bags so that each item is equally distrusted among the gift bags . Find the number of each item in a gift bag

57 pens per bag

21 pencils per bag

9 erasers per bag

Step-by-step explanation:

Here, we are to distribute a specific portion of each of the items in each of the gift bags.

What we must take into consideration is that the number of items per gift bag must be equal.

Thus, what we do is to divide the total number of each item by 3 to get exactly the number of each items that would be in each of the gift bags

For the pens, we have 171/3 = 57 pens per bag

For the pencils, we have 63/3 = 21 pencils per bag

For the erasers, we have 27/3 = 9 erasers per bag

a 10 percent increase

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.
