Answer:
The total number of visitors on Thursday was 400.
Step-by-step explanation:
So, we know that there were 220 visitors who were under the age of 12, and that the amount of visitors under the age of 12 was 55% of the total number of visitors. This means that 220 was 55% of the number of visitors. To find the total number of visitors, we divide the number of visitors under the age of 12 (220) by 0.55 (55%).
220/0.55 = 400
The total number of visitors on Thursday was 400.

Answer:
d
Step-by-step explanation:
Y = m x + b , where m is the slope. The slope is the rise over the run or the change in x ( rooms cleaned ) over the change in y ( cost ).
125 = m * 1 + b
175 = m * 2 + b
-----------------------
b = 125 - m
175 = 2 m + 125 - m
m = 175 - 125
m = 50 ( the rate of change ), b = 75
The formula is: y = 50 x + 75
It means that the starting cost will be $75 and that for every room cleaned, the cost will rise for $50.
