Two large lemonades cost 2.18 and three small lemonades cost 2.22. If jacob bought five large lemonades and two small lemonades, how much did he pay in total

Question

I don't understand how much the price for the lemonade would be of he bought five and two 

Answer 1

The problem is about Unit Values.

 

"Two large lemonades cost 2.18,"  so one large lemonade cost 1.09, or 1.09 per large lemonade

 

"three small lemonades cost 2.22," so one small lemonade cost 0.74, or 0.74 per small lemonade.

 

 

The cost for each group (large or small) is (unit cost)*(number of items)

 

    Large lemonades             +      Small lemonades              =     Total cost

        (1.09)(5)                    +      (0.74)(2)                         =       6.93
