Question

Leonard it sells small watermelons for seven dollars each and large watermelons for $10 each one day the number of small watermelons he saw was 15 more than the number of large watermelons and he made a total of $394 how many small and how many large watermelons a did he sell?

Answer 1

17 large 32 small
15 small=$105
10L +7S(L)= 394-105
Once we know the 15 extra for small it should be equal number on the left side That’s why I changed S into L
17L =289
L=17
L=$170

394-170=224
224/7=32
