There are 42 refrigerators in the train car that can hold up to 7, 100 kilograms. Each refrigerato has a mass of 125 kilograms. Elliot wants to solve for n, the number of additional refrigerators the train car can hold.
Step 1:125(n+42)≤ 7,100
Step 2: n+42≤ 56.8
Step 3: n≤ 14.8
Elliot concludes that the train car can hold up to 15 more refrigerators.
Is Elliot's conclusion correct?
The problem can be modeled with the inequality_____
