Mrs. Dimas has $130 to but basketballs for Edison Middle School. How many can she buy at $15 each? interpret the reminder

you can't go over budget

cost=cost per backetball times number of basketbals

cost=15 times b

cost≤130

15b≤130

divide both sides by 15

b≤8 and 10/15

b≤8 and 2/3

round down because you can't buy 2/3 basketball

buy 8

the remainder means you have 2/3 of $15 left or $10
