If you purchase 27 guppies, and the increase rate of 35% per year,how many guppies will you have after 3 years
dem82 [27]

Answer:

66

Step-by-step explanation:

<u>year 1: 35% of 27</u>

convert 35% into a decimal :0.35

0.35 x 27= 9.45

27+ 9.45= 36.45 , thats what you have left at the end of year 1

<u>year 2: 35% of 36.45</u>

0.35 x 36.45= 12.7575

36.45 + 12.7575= 49.2075, thats whats left at the end of year 2

<u>year 3: 35% of 49.2075</u>

0.35 x 49.2075= 17.222625

49.2075+ 17.222625= 66.430125, thats whats left at the end of the 3rd year.

you cant have 66.430125 of a guppy so it rounds to a whole number- 66

let me know if this was helpful :)
