Len won a gift card for
100 cups of tea. He orders
the same number of cups
each month. After a year,
he has 16 cups leht. How
many cups did he order
each month?

Answer 1

7

Explanation:

Let x be the amount of cups he ordered per month.

There are 12 months in a year.

Therefore, 12 times x plus 16 (the amount he has left) must equal to 100. Thus:

`12x+16=100`

Subtract 16 from both sides:

`12x=84`

Divide both sides by 12:

`x=7`

Therefore, Len ordered 7 cups of tea per month.
