Question

Sidney already has 2 plants in her backyard and she can also grow 5 plants with every seed packet she uses. How many seed packets does Sidney need to have a total of 22 plants in her backyard?

a) 4
b) 6
c) 8
d) 10

Answer 1

Sidney needs 4 seed packets to reach her goal of 22 plants (option a).

Step-by-step explanation:

Calculate the number of plants Sidney needs to grow: 22 total plants - 2 existing plants = 20 plants to grow.

Divide the number of plants needed by the plants grown per seed packet: 20 plants / 5 plants/packet = 4 packets.

Therefore, Sidney needs to purchase 4 seed packets to grow enough plants and reach a total of 22 in her backyard.

In conclusion, by determining the number of plants Sidney needed to grow and considering the yield per seed packet, we determined that 4 seed packets are required to achieve her desired total of 22 plants.

Option A is answer.

Answer 2

Sidney needs 4 seed packets to have a total of 22 plants in her backyard. She already has 2 plants, and each seed packet grows 5 plants, so 4 seed packets will yield the 20 additional plants needed.The correct answer is a) 4.

Step-by-step explanation:

To determine how many seed packets Sidney needs to have a total of 22 plants in her backyard, we can set up an equation. Sidney already has 2 plants, so she needs an additional 20 plants to reach 22. Since each seed packet allows her to grow 5 plants, we need to find out how many times 5 goes into 20 to know the number of seed packets required.

The equation can be written as:

2 + 5x = 22,

where 'x' represents the number of seed packets.

Solving for 'x', we subtract 2 from both sides of the equation to get:

5x = 20,

Divide both sides by 5:

x = 20 / 5,

x = 4.

Therefore, Sidney needs 4 seed packets to have a total of 22 plants in her backyard.

The correct answer is a) 4.
