Clare finally got permission from her parents to paint her bedroom purple, and she can't wait to start! She decides to get 1 gallon of paint for the walls, 2 quarts for the ceiling, and 1 quart for the trim. Just to be safe, she also wants to get an extra quart of paint. How many gallons of purple paint should she buy in all?

2 gallons

Step-by-step explanation:

There are 4 quarts in a gallon. She buys 1 gallon and 4 quarts, which is a total of 2 gallons. Hope this helps!

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.
