Question

How many Christmas trees were sold on sat and sunday?

Answer 1

103 christmas trees.

Explanation:

total trees sold in the first five days:

`27 * 5 = 135`

total trees sold in this week:

`34 * 7 = 238`

The answer is:

`238 - 135 = 103`

Answer 2

Hello :D

Let's form an equation:

x/5 = 27

Let's form another equation:

(x+y)/7 = 34

Rearrange equation one so it is x = 27 x 5 = 135

Now we can substitute this value into equation 2:

(135 + y)/7 = 34

135 + y = 238

y = 238 - 135

y = 103

Answer is 103
