For a fairground ride the maximum weight of a person is 100kg to the nearest kg. What is the maximum a person can weigh to go on the ride safely

The maximum a person can weigh to go on the ride safely is 100.5 kg

Step-by-step explanation:

The specification for the maximum weight of each person that goes on the ride = 100 kg

Therefore, given that the maximum possible error of a measurement is equal to 1/2 multiplied by the unit of measurement, we have that the specified maximum weight, , can be written as follows;

= (100 ± 0.5) kg, which gives the maximum a person can weigh to go on the ride safely as 100 kg + 0.5 kg = 100.5 kg

the answer is $42.96

step-by-step explanation:

6 adults and 9 children went.

a + c = 15

12a + 9c = 153

12(6) + 9(9) = 153

72 + 81 = 153
