Hey there, Guest!

Let's call x=number of masks Becky's brother made.

We know Becky made 30% less than the number of masks her brother made.

30% of x is calculated by:

30*x/100 = 0.3x

Now subtracting from x:

x - 0.3x = 0.7x

Becky made 63 carnival masks, this means that:

0.7x = 63

Dividing by 0.7:

x = 63/0.7 = 90

Becky's brother made 90 masks.

Now add 63 together with 90 to get 153 masks.

Hope this helped!
