To solve this problem, we need to determine the value of x, which represents the number of cups of coffee that can be brewed from 1 lb. of coffee.
Let's break down the information given:
Amount of coffee bought: 3 lbs.
Number of cups of coffee Angie drinks per day: 3 cups
Number of days the coffee will last: 40 days
We can set up the equation as follows:
Amount of coffee bought * Number of cups of coffee per lb. of coffee = Number of cups of coffee Angie drinks per day * Number of days the coffee will last
3 * x = 3 * 40
Let's simplify and solve for x:
3x = 120
To isolate x, we divide both sides of the equation by 3:
3x / 3 = 120 / 3
x = 40
The value of x is 40. Each lb. of coffee will brew about 40 cups of coffee.
#### 40
The answer is: 40
