Answer:
1. R = 20%, B = 40, P = 8
2. R = 45%, B = 1200, P = 540
2. R = 13%, B = 300, P = 39
4. R = 85%, B = 40, P = 34
5. R = 30%, B = 120, P = 36
Step-by-step explanation:
PERCENTAGE (P=BxR) - The result obtained when a number is multiplied by a percent. BASE (B=P/R) - The whole in a problem. The amount you are taking a percent of. RATE (R=P/B) - The ratio of amount to the base.
P = it is associated with "is" in the statement
B = associated with "of"
R = with %
