Answer:
There are 3 green marbles in the box.
Step-by-step explanation:
15% = 0.15
To figure out how much 15% of 21 is, you must multipl the decimal form of the percentage by the whole number. This will give you how much of that number that percentage is.
0.15 * 21 = 3.15
But you can't have 0.15 of a marble, so you must round as well.

Answer: the sum invested = $600
<u>Step-by-step explanation:</u>
Interest (I) = Principal (P) × rate (r) × time (t)
Original amount: I = P × r × 3
Increased by 1%: I + 18 = P × (1+ .01)r × 3
Substitute I with Prt and set the equations equal to each other to find r:
3Pr + 18 = 3.03Pr
Solve for Pr:
18 = 0.03Pr
<u> ÷0.03</u> <u>÷ 0.03 </u>
600 = Pr
Answer:
