Answer: it will cost $7775 to transport 19 tons of sugar.
Explanation:
let S represent the amount of sugar (in tons) transported.
Let C represent the total cost of transporting S tons of sugar. It will cost $3500 to rent trucks, and it will cost an additional $225 for each ton of sugar transported. The expression for the total cost would be
C = 225S + 3500
To transport 19 tonnes of sugar, the total cost would be
C = 225 × 19 + 3500
C = 4275 + 3500
C = $7775
