Equation: #40.44x<=75#
Pictures Max can buy: 1

In this problem, #x# represents the amount of pictures Max can buy. So, #x(39.95+0.49)<=75#.
#40.44x<=75#.

#x=75/40.44#

Now, #75/40.44# approximates to 1.85, but we have to round down, so Max can buy only one picture.

We can check:

#1(40.44)<=75#.

#80.88# is greater than 75.

Therefore, Max can buy one picture.
