Question

Let HH represent the number of hummingbirds and SS represent the number of sunbirds that must pollinate the colony so it can survive until next year.

6H+4S > 746H+4S>74
This year, 88 hummingbirds pollinated the colony. What is the least number of sunbirds that must pollinate the colony to ensure that it will survive until next year?

Answer 1

S > 6.5 means a minimum of 7 sun birds must pollinate.

Explanation:

Let H represent the number of hummingbirds and S represent the number of sun birds that must pollinate the colony so it can survive until next year.

Now the given inequality is :

`6H+4S>74`

This year, 8 hummingbirds pollinated the colony, means we will put H = 8 in the inequality.

`=> 6(8)+4S>74`

`=> 48+4S>74`

`=> 4S>74-48`

`=> 4S>26`

Hence,
`S>6.5`

This, means a minimum of 7 sun birds must pollinate.

Answer 2

Answer: 7

Explanation:

Here the given inequality that shows the number of humming birds(H) and the number of sunbirds(S) that must pollinate the colony so it can survive until next year,

6 H + 4 S > 74

If This year, 8 hummingbirds pollinated the colony.

By putting H=8 in the above inequality,

We get,

6× 8 + 4 S > 74

⇒ 48 + 4 S > 74

⇒ 4 S > 26

⇒ S > 6.5

Hence the least number of sunbirds is 7.
