Question 1065824: Christine's parents gave her $70 to spend at the Topsfield Fair. She spent $10 on flowers. If each antique flower vase at the fair costs $3 each, solve the inequality 10+3a≤70
10+3a≤70
to determine how many antique flower vases Christine can buy.
how would I solve this?

You can put this solution on YOUR website!
a= number of lower vases, in $
3a= cost of a flower vases, in $
10%2B3a= cost of $10 worth of flowers plus a vases
10%2B3a%3C=70 says that the cost of Christine's flowers and vases purchase
must be less than, or at most equal to %22%24+70%22 .
Subtracting 10 from both sides of the inequalour
gives us an equivalent inequality:
3a%3C=70-10 <---> 3a%3C=60
Multiplying (or dividing) both sides by a positive number
gives us an equivalent inequality, so
a%3C=60%2F3 <---> highlight%28a%3C=20%29 .
