Question

Ariel can grow 2 plants with every seed packet. How many seed packets does Ariel need to have a total of 10 plants in her backyard? 

 

Answer 1

The number of plants depends on the number of seed packets.

 

Let x = number of seed packets

Let y = number of plants

 

2 plants for each seed packet is the plant rate per seed packet.  Therefore, the plants and seed packets have a linear relationship.

 

y = 2x

 

To find out how many seed packets she needs for a total of 10 plants, set y=10 and solve for x.

 

10 = 2x

 

Solve for x from this equation.

Answer 2

Hi Tom

 

If you obtain 2 plants per seed packet, then

 

10 plants / 2 plants per packet = the number of packets needed.
