It will cost $4200 to rent trucks, and it will cost an additional $150 for each ton of sugar transported.

Question

Please help with what the equation is and how to solve

Answer 1

Not a very elegantly worded question.  Perhaps the total cost will be $4200 + 150n if n is the number of tons of sugar.

 

I'll bet that this question is from newish Common Core material rather than from a well vetted textbook, where more realistic situations and precise language would be found.)
