Shelia buys flower bulbs from a catalog $2 each and $4 shipping charge for the whole order. She spends $20 on flower bulbs. The model can be used to describe x, the number of bulbs Shelia can order. Write an equation to determine the number of bulbs Shelia can order. How many bulbs did she order?

8 bulbs

Step-by-step explanation:

Step one:

Given data

Shelia buys flower bulbs from a catalog for $2 each and $4 shipping charge for the whole order

we are told that the total money spent is $20

let the number of bulbs ordered be x, and the total money spent be y

the equation for the situation is

y=2x+4

for a total amount of $20, we want to find x

20=2x+4

20-4=2x

16=2x

divide both sides by 2

x= 16/2

x= 8 bulbs
