Ashley had a summer lemonade stand where she sold small cups of lemonade for 1.25 and large cups for 2.50. if ashley sold a totak of 155 cups of lemonade for 265, how many cups of each type did she sell?

Let S be the number of small cups and L the number of large cups sold 

1.25 ·S +2.50·L=265
S+L=155 or we can say that S=155-L 

in the first equation substitute S for 155-L
1.25 (155-L)+2.50L=265
193.75-1.25L+2.50L=265
1.25L=265-193.75
L=71.25/1.25= 57
S=155-L=155-57=98

Ashley sold 98 small cups and 57 large cups of lemonade

Idon’t know but hope this you
