Answer:
4
Step-by-step explanation:
19 = 7 + 3r
12 = 3r
4 = r
Given:
Original or base : 40
New amount : 72
We need to find the difference of the new amount and the original amount
72 - 40 = 32
We then divide the difference by the original amount
32/40 = 0.80
We multiply the quotient by 100%
0.80 x 100% = 80%
The percentage of change is 80%
