Answer:
Step-by-step explanation: To find the total cost, we multiply the cost of one bulb by the number of bulbs: $0.79/bulb × 37 bulbs (since he plants 37 bulbs in one row) × 3 rows = $0.79 × 37 × 3 = $ ~87.51 Therefore, Derrick spends approximately $87.51 on bulbs.

Answer:
87.51
Step-by-step explanation:
First, let's convert the length of the garden to a mixed number. The given length is 18 1/2 feet. We can rewrite this as 18 + (1/2) = 18.5 feet.
Next, we need to convert the distance between each bulb to the same unit as the length of the garden. The given distance is 3/8 of a foot.
To do this, we can find a common denominator between 2 (since 1/2 has a denominator of 2) and 8.
The least common denominator (LCD) is 8, so we need to multiply 2 by 4 and 8 by 1 to have a common denominator of 8. This gives us 1/2 (multiplied by 4/4) and 3/8 (multiplied by 1/1).
Now, the distance between each bulb is 4/8 of a foot, which simplifies to 1/2 of a foot.
To find out how many bulbs Derrick can plant in one row, we divide the length of the garden by the distance between each bulb:
18.5 feet ÷ (1/2) foot = 18.5 ÷ (1/2) = 18.5 × 2 = 37 bulbs
Therefore, Derrick can plant 37 bulbs in one row.
2) Now, let's calculate how much money Derrick spends on bulbs.
We know that the cost of each bulb is $0.79, and Derrick plants three rows of bulbs.
To find the total cost, we multiply the cost of one bulb by the number of bulbs:
$0.79/bulb × 37 bulbs (since he plants 37 bulbs in one row) × 3 rows = $0.79 × 37 × 3 = $ ~87.51
Therefore, Derrick spends approximately $87.51 on bulbs.
