Step-by-step explanation:

Bill's answer is wrong because timesing 150 by 1.3 is increasing the number by 30%, not 3%

If he wanted to use this method, he would have ti times 150 by 1.03

154.5

Step-by-step explanation:

Bill's method is wrong since 3% is equivalent to 0.03 or 3/100 and not 1.3 so this is where the mistake is. Moreover, Bill's method is not only wrong but also incomplete.

In order to increase 150 by 3% you will have to determine how much is 3% of 150 to have it increased by that specific amount.

Calculations:

150 x 0.03 = 4.5

Now that we know 4.5 is 3% of 150, we can add 4.5 to 150 to increase it by 3%.

150 + 4.5 = 154.5

answer is : muchas/tipicas

have a nice day!
