(3/4)x + (5/8) x =4x

.75. .625

.75x +.625x = 4x

1.375x = 4x

subtract 4x from each side because you want to get like terms (x) together.

equation is now
1.375-4x= 0

-2.625x= 0


-2.625× = 0
------------- -----------
-2.625 -2.625

zero can't be divided by anything so

x=0

The average number of customers per day increased 25 percent during the sale. If the average number of customers per day before
Rasek [7]

Answer:

The average number of customers per day during the sale was 150.

Step-by-step explanation:

This question can be solved using a rule of three.

Before the sale, the average number of customers per day was 120, which is 100% = 1.

Now, there are x customers, and since it is an increase of 25%, it is 100+25 = 125% = 1.25. So

120 - 1

x - 1.25

x = 1.25*120 = 150

The average number of customers per day during the sale was 150.
