Becky made 63 carnival masks, which is 30% less than the number her brother made. How many carnival masks did becky and her brother make in total?
+373 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!
