<u>Step-by-step explanation:</u>
Here we have , A customer at a store paid $64 for 3 large candles and 4 small candles. At the same store, a second customer paid $4 more than the first customer for 1 large candle and 8 small candles. The price of each large candle is the same, and the price of each small candle is the same. We need to find Which system of equations can be used to find the price in dollars of each large candle, x, and each small candle, y . Let's find out:
Let the price in dollars of each large candle, x, and each small candle, y .So
A customer at a store paid $64 for 3 large candles and 4 small candles

Answer:
Step-by-step explanation:
Given
Solving (a): The mean
Mean is calculated as:
This gives:
Solving (b): The median
Sort the data in ascending order:
The median is:
The 8th item on the sorted dataset is 7; So:
Solving (c): The mode
Because it has a frequency of 3 (more than any other element of the dataset).
