Answer:
x + y тЙе 26 + 15
5x + 8y тЙе 250 (see below)
Step-by-step explanation:
First, write an equation to represent the total cost to wash cars:
$5x = cost for cars
Then, write another for trucks:
$8y = cost for trucks
If the question is saying that they will wash at least 26 cars and 15 trucks, that means they could wash more. This means that we'll need an inequality:
This inequality represents that the total number of cars and trucks they wash will be at leastтАФwhich means that it is equal to or greater thanтАФthan the amount given:
x + y тЙе 26 + 15
Any equation or inequality with two unknowns is not solvable, meaning we need a system of equations:
If they make at least $250, that means that we need to combine the costs of the cars and trucks to make an inequality:
5x + 8y тЙе 250
Now you have your system of equations:
x + y тЙе 26 + 15
5x + 8y тЙе 250
