Answer:
1.) 150
2.) 120%
3.) 13
4.) 150
5.) 200
Step-by-step explanation:
FINDING THE PERCENTAGE
1.) To find the percentage (P),you apply the formula P = R × B
FINDING THE RATE
2.) This time you solve for the unknown value of R (expressed in percent) when both B and P are known.You can use the same formula in order to solve for R. Since it is known that P = R × B,then R can be computed by using the formula R = P/B × 100 or R = (P ÷ B) × 100. You multiply it by 100 so that the answer will be in percent.
FINDING THE BASE
3.) If the R and P are known, then the B can be solved using the formula B = P/R or B = P ÷ R.
