Raquel is mixing lemon-lime soda and a fruit juice blend that is 45% juice. If she uses 3 quarts of soda, how many quarts of fruit juice must be added to produce punch that is 30% juice?

Raquel is mixing lemon-lime soda and a fruit juice blend that is 45% juice. If she uses 3 quarts of soda, how many quarts of fruit juice must be added to produce punch that is 30% juice?
----------------
3*0 + 0.45j = 0.2*(3 + j)
0.45j = 0.2*(3 + j)
45j = 20*(3 + j) = 60 + 20j
25j = 60
j = 60/25
j = 2.4 quarts
