The dolphins at the San Diego zoo eat 3 1/8, start fraction, 1, divided by, 8, end fraction buckets of fish each day. The killer whales eat 2 3/5 2, start fraction, 3, divided by, 5, end fraction times as much fish as the dolphins. How many buckets of fish do the killer whales eat each day?

The killer whales eat buckets each day.

Step-by-step explanation:

GIven: Dolphins eat fish each day.

Since,

The killer whales eat  times as much fish as the dolphins.

Since,

The number of buckets of fish, the killer whales eat each day

The killer whales eat buckets each day.

the answer is simply just 6n add the two together as they have an n

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.
