Question

The line plot shows the amount of grass seed that a landscaper needs for each of her jobs. What is the total amount of grass seed that the landscape needs?​

Answer 1

`Total = 18(1)/(4)`

Explanation:

Given

The attached line plot

Required

The total

To do this, we simply multiply each grass seed by the frequency (i.e. number of dots), then add up the results.

So, we have:

`Total = (1)/(4) * 2 + (1)/(2) * 3 + (3)/(4) * 1 + 1 * 2 + 1(1)/(4) * 1 + 1(1)/(2) * 3 + 1(3)/(4) * 1 + 2 * 3`

`Total = (1)/(2) + (3)/(2)+ (3)/(4) + 2 + 1(1)/(4) * 1 + 1(1)/(2) * 3 + 1(3)/(4) * 1 + 2 * 3`

Convert fractions to improper fraction

`Total = (1)/(2) + (3)/(2)+ (3)/(4) + 2 + (5)/(4) * 1 + (3)/(2) * 3 + (7)/(4) * 1 + 6`

`Total = (1)/(2) + (3)/(2)+ (3)/(4) + 2 + (5)/(4) + (9)/(2) + (7)/(4) + 6`

Add fractions

`Total = 18(1)/(4)`

Hence, the total amount is:
`18(1)/(4)\b` pounds
