You sell lemonade for $2 per cup and orange juice got $3 per cup. you sell a total of 100 cups for $240. how cups of lemonade and orange juice were sold?

240

Step-by-step explanation:

lets see

if we sell 100 cups of lemonade that would make 200 dollars NOT ENOUGH

if we sell 100 cups of orange juice that would make 300 TOO MUCH

meaning we have the find the right one

lets say if we sell 80 lemonade cups we would make 160 then have 20 orange juice which would make 60 and 160+60= 220 so not enough either

this means we can't have as much lemonade

lets try 75 cups of lemonade

lets say if we sell 50 lemonade cups we would make 100 then have 50 orange juice which would make 150 and 150+100= 250 so too much

lets try 55 cups of lemonade

lets say if we sell 55 lemonade cups we would make 110 then have 45 orange juice which would make 135 and 110+135= 145

sooo close

try 60

60*2-120 40*3-120

120*120= 240

you can not solvr this without numbers
