1. Some students decide to have a car wash to raise money for a local charity. The students decide that they want to raise at least $550. The fee the students charge for washing a car is $10, whereas the fee for washing a truck is $14. Determine a linear inequality to represent the combination of cars (c) and trucks (t) the students can wash to raise the desired amount of money for their charity.
we must put together the inequality taking into account the price of car and truck washing, and the desired quantity to be achieved. which must be at least $550, therefore:
