Question

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.

Answer 1

We have the following:

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:

`10\cdot c+14\cdot t\ge550`
