Final answer:
By setting up an equation with x representing the cost of each bulb and accounting for the $12 spent on potting soil, we found that Marco paid $3 for each flower bulb.
Step-by-step explanation:
To solve the problem of figuring out how much Marco paid for each bulb, we'll set up an equation using x to represent the cost of each bulb. First, we know that Marco spent $12 on potting soil and had a total spending of $144. Deducting the cost of the soil from the total, we have $144 - $12 = $132 left for the bulbs. Next, we set up our equation. Since Marco bought 44 bulbs, we multiply the cost per bulb by the number of bulbs to find the total cost spent on bulbs:
44x = $132
Now, divide both sides by 44 to find the cost per bulb:
x = $132 / 44
x = $3
So, Marco paid $3 for each bulb.
