Answer 1

To find the answers, we need to use the given data and solve equations to determine the various quantities asked in the question.

Step-by-step explanation:

The given question provides information about the results of a survey conducted at a Lunar New Year celebration in Chinatown. We can solve the various parts of this question using the given data.

(a) How many attended?

We know that the total attendees are either locals or visitors. Let's represent the number of locals as L and the number of visitors as V. From the given data, we have:

L = 114

L + V = total attendees

V - (113 - 78) = total visitors who lit firecrackers

Solving these equations will give us the total number of attendees.

(b) How many of those who attended did not speak Cantonese?

To find the number of attendees who did not speak Cantonese, we can subtract the number of Cantonese-speaking attendees from the total number of attendees.

(c) How many locals did not light firecrackers?

To find the number of locals who did not light firecrackers, we can subtract the number of locals who lit firecrackers from the total number of locals.

(d) How many of those who lit firecrackers were Cantonese-speaking visitors?

To find the number of Cantonese-speaking visitors who lit firecrackers, we can subtract the number of locals who lit firecrackers from the total number of visitors who lit firecrackers.
