It used 560 kilograms of sugar last month
Step-by-step explanation:
The given is:
- A coffee shop used 30% more sugar this month than last month
- The coffee shop used 728 kilograms of the sugar this month
We need to find how much it used last month
Assume that the coffee shop used x kg sugar the last month
∵ The coffee shop used x kilogram of sugar last month
∵ It used 30% more sugar this month than last month
- Find the value of 30% of x and add it to x to find how many
kilograms it used for this month
∵ 30% of x = [tex]\frac{30}{100}[/tex] × x = 0.3 x
∴ It used this month = x + 0.3 x
∴ It used this month = 1.3 x kg
∴ The coffee shop used 1.3 x kilograms of sugar this month
∵ The coffee shop used 728 kilograms of the sugar this month
- Equate 1.3 x by 728 to find x
∴ 1.3 x = 728
- Divide both sides by 1.3
∴ x = 560
It used 560 kilograms of sugar last month
