Harry the hippo is munching on the lily pads in his pond. when he arrived at the pond, there were 20 lily pads, but he is eating 4 lily pads an hour. heinrick the hungrier hippo found a better pond with 29 lily pads! he eats 7 lily pads every hour.

part a.) if harry and heinrick start eating at the same time, when will their ponds have the same number of lily pads remaining?

( answer this one)

part b.) how many lily pads will be left in each pond at the same time.

After the 3rd hour

8 lily pads

Step-by-step explanation:

This is quite straight forward and require no deep mathematics.

Harry has 20 lily pads to eat and he eats 4 per hour. After the first hour, he eats 4 and he has 16 left. After second hour, he eats another 4 and he has 12 left. After third hour, he eats four and has eight left.

For Hennrick, he has 29 lily pads and he eats 7 per hour. After first hour, he has 22 left. After second hour, he eats another 7 and have 15 left. After 3rd hour, he eats another 7 and has just 8 left.

8 lily pads will be left at the same time

f(x) is going down by 4

step-by-step explanation:

(its either that or its going left by 4)
