Answer:
300
Step-by-step explanation:
The total number of desserts is x. we don't know what it is.
40% of all the desserts are cookies.
That is 40% of x.
We are told that 120 of the desserts are cookies.
That means that 40% of all desserts amount to 120.
40% of x = 120
0.4x = 120
Divide both sides by 0.4
0.4x/0.4 = 120/0.4
x = 300
