Given :
Miki possesses 104 nickels and 88 dimes. She intends to sort her coins into sets where each set has an equal count of both nickels and dimes.
Last year, 216,000 cars were sold.
To Find :
An equation that can identify the number of trucks, t, sold the previous year.
Solution :
Let t represent the quantity of trucks sold and c represent the cars sold.
The statement indicates that the quantity of cars sold exceeded three times the trucks sold by 39,000.
Thus,
Plugging the value of c = 216000 into the equation above yields :
This gives us the solution we seek.
