In Math camp, 144 problems were solved in two days. The number of problems solved on the second day is 80% of the number of problems solved during the first day. How many problems were solved on the first day?
To find the number of problems solved on the first day, let's assume the number of problems solved on the first day is "x".
According to the information given, the number of problems solved on the second day is 80% of the number solved on the first day. That means the number solved on the second day is 0.8x.
We know that the total number of problems solved in two days is 144. So, the equation becomes:
x + 0.8x = 144
Combining the like terms, we simplify the equation:
1.8x = 144
To find x, we need to divide both sides of the equation by 1.8:
x = 144 / 1.8
Evaluating this expression gives us:
x = 80
Therefore, 80 problems were solved on the first day.
