Answer:
52 or 50 depending on how your teacher wants it
Explanation:
first we want to find out how many sets of 5 there are, this answer will be different deepening on how you want it answered
26/5=5.2
5.2*10=52
not quite sure but it's $52 if he can charge per bag on top of the 5 or 50 if he is only charging per 5 bags
if he only charges for 5 bags we do 26/5=5.2 so round down to 5 then 5*10=50
hope this helps
