Mr lim bought some notebooks that cost $5 each andsome markers that cost $2.the number of markers was3 more than 2 times the notebooks. mr lim paid $42 for the notebooks and markers .how many notebooks did mr lim buy?

4 Notebooks

Step-by-step explanation:

The number of notebooks is x, the number of markers is 2x+3.

Since the price per notebook is $5 we can write it as 5x, And the price per marker is $2, we can write that as 4x+6

5x+4x+6=42

9x=36

x=4

so he bought 4 notebooks and 11 markers.

CHECK: 4*5=20 and 11*2=22 20+22=42
