Question

(Equation)

Answer 1

Answer:

7

Step-by-step 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.
