Answer: Required equation: 400+25x = 2100
Variable: x = Number of days to donate 2100 pounds.
Step-by-step explanation:
Let x = Number of days.
y = Total pounds of food donated in x days.
Given: Initial amount of food = 400 pounds
Pounds of food donated per day = 25
Total food = Initial amount of food + (Pounds of food donated per day ) (Number of days)
y = 400+25x
Their goal is to collect 2100 pounds.
2100 = 400+25x [Substitute y= 2100]
Required equation: 400+25x = 2100
Variable: x = Number of days.
