Question

The cost to enter a water park increases from 56$ per person to 73$ per person. By what percent did the entry fee cost?

Who wrote it correctly?

Joseph
17/56 = x/100

Kevin
17/73 = x/100

Alex
129/56 = x/100

Abdul
129/73 = x/100

Answer 1

To calculate the percent increase, you need to divide the increase in cost (73 - 56 = 17) by the original cost (56) and multiply by 100 to express it as a percentage. So, Joseph and Abdul have written the correct formula:

Abdul: 129/73 = x/100.
Joseph: 17/56 = x/100.
