X - 9 + 2wx = y Add 9 to both sides
x + 2wx = y + 9 Factor out the x
x (1 + 2w) = y + 9 Divide both sides by (1 + 2w)
x = (y + 9) / (1 + 2w)
Answer:the total number of milkshake that the ice cream shop sold that day is 120
Step-by-step explanation:
Let x represent the total number of
vanilla milkshakes that the ice cream shop sold that day.
The ice cream shop sold 48 vanilla milkshakes in a day which is 40% of the total number of milkshake sold that day. It means that
40/100 × x = 48
0.4 × x = 48
0.4x = 48
x = 48/0.4 = 120
