Question

did Elizabeth spend making jam if she jarred 9 liters of jam? Write and solve an equation to find the answer.

Answer 1

Number of days Elizabeth spend making jam if she jarred 9 liters of jam is 4 days

Solution:

Given that, Elizabeth has already jarred 1 liter of jam

She will jar an additional 2 liters of jam every day

To find: Number of days Elizabeth spend making jam if she jarred 9 liters of jam

Let "x" be the number of days Elizabeth spend making jam

Then, by given information, we frame a equation as,

9 liters of jam = 1 liter of jam + 2 liters of jam( "x" days )

$9 = 1 + 2x\\\\9 - 1 = 2x\\\\2x = 8\\\\x = 4$

Thus she spend 4 days in making jam
