Question

Lisa needs 250 yards of yarn to knit a hat. She has 185 yards of yarn and needs to buy the rest. How many yards of yarn does she need to buy?

Use the variable y to represent the number of yards of yarn she needs to buy.

Which equation represents this situation and its solution?


y + 250 = 185; y = 65

y + 185 = 250; y = 65

250y = 185; y = 55

185y = 250; y = 55

Answer 1

the 2nd one is the answer...

Answer 2

Option B.

Explanation:

It is given that Lisa needs 250 yards of yarn to knit a hat.

She has 185 yards of yarn and needs to buy the rest.

Let y to be the number of yards of yarn she needs to buy.

Number of yards of yarn she needs to buy + Number of yards of yarn she has = 250

`y+185=250`

Subtract 185 from both sides.

`y+185-185=250-185`

`y=65`

The required equation is
`y+185=250` and solution is
`y=65`.

Therefore, the correct option is B.
