inequality is 0.15t+0.10m=35
I need all of the possible combinations. so far I only have
0.15(30)+0.10(305)=35
and
0.15(0)+0.10(350)=35
you do not have to show work but it has to equal to 35 and use 0.15 and 0.10
and I'm sure I can do the next part which is finding 5 possible combinations of t and m that would keep it under 35 xD thank you.

This is called a Diophantine Equation
if you want only integer solutions.
Otherwise it is a routine linear equation:
15 t + 10 m = 3500 (to get rid of fractions)
Divide by 5
3t + 2m = 700
m = (700 - 3t) / 2
Actually because of the small coefficients,
you can generate integer solutions easily.
Just need t to be even ...
t .... m
0 ... 350
2 ... 347
4 .... 344
... and so on
In general
t = 0 + 2x
m = 350 - 3x
for any integer (or non-integer for that matter) value of x.
x ... t ... m ... .15*t+.10*m
