Answer:
8 bulbs
Step-by-step explanation:
In the model, each + represents a dollar
4 +s for the shipping cost, 20 +s for the total cost.
Therefore we have 2x (since each bulb is $2) + 4 = 20
2x = 16
x = 8
x is the number of bulbs.
We have $2x + $4 = $20.
=> $2x = $16, x = 8.
Hence Sheila can order 8 flower bulbs.
