Question

In Math camp 144 problems were solved in two days.

Answer 1

Answer:

80 questions.

Step-by-step explanation:

-Let X be the number of problems solved on day 1.

-Questions solved on day 2 are:

$=80\%\times x\\\\=0.8x$

We know that the total number of questions solved is 144:

$x+0.8x=144\\\\1.8x=144\\\\x=80$

Hence, the number of questions solved on the first day is 80
