Final answer:
To determine how many tulip bulbs Julie can buy and have shipped, set up the equation 0.50b + 4.50 = 22 and solve for b. Julie can buy and have shipped 35 tulip bulbs.
Step-by-step explanation:
To determine how many tulip bulbs Julie can buy and have shipped, we can set up an equation using the given information.
Let b be the number of bulbs Julie can buy.
The cost of each bulb is $0.50.
The one-time shipping cost is $4.50.
Julie has $22 to spend.
We can write the equation:
0.50b + 4.50 = 22
To solve for b, we can subtract 4.50 from both sides:
0.50b + 4.50 - 4.50 = 22 - 4.50
0.50b = 17.50
To isolate b, we can divide both sides by 0.50:
b = 35
Julie can buy and have shipped 35 tulip bulbs.
