TWO PARTS:
1)Derrick's garden is 18 1/2 feet long. He plants bulbs 3/8 of a foot apart. How many bulbs can Derrick plant in one row?
2)Derrick plants three rows of bulbs that cost $0.79 each. How much does he spend on bulbs?
Thank You!!
This doesn't help me.
18.5 / (3/8) = 49 1/3
so 49 because it is hard to plant 1/3 bulb
3 * 49 = 147
147 * 0.79 = 116.13 before tax :)
Thank you it helped me a lot. It really makes sense now that I saw this.
1) To find out how many bulbs Derrick can plant in one row, we need to divide the length of the garden by the distance between each bulb.
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.
