+58 Remus bought a mug and 4 towels for $13. Joanne bought a mug and 7 towels for $19. Find the cost of the mug.
The difference in total cost is the cost of the extra towels.
+240 Let's put this into equations,
m+4t=13
m+7t=19
Subtracting the equations we get,
3t=6
t=2
Now we know the cost of a towel, we can plug it back into one of the equations.
m+8=13
m=5
So a mug costs 5 dollars.
