Hello!
To find the mean of the given numbers, you would add up all of the given values, and divide by how many numbers were given. In other words, it is the sum divided by the count.
Since each supermarket raised it's price by $0.05, we need to add that value to each of the price of a loaf of bread at the five supermarkets.
Supermarket 1: $1.44 + $0.05 = $1.49
Supermarket 2: $1.59 + $0.05 = $1.64
Supermarket 3: $1.69 + $0.05 = $1.74
Supermarket 4: $1.47 + $0.05 = $1.52
Supermarket 5: $1.61 + $0.05 = $1.66
After calculating the increased prices of the loaves of bread at each supermarket, we add each price, and divide by 5.
($1.49 + $1.64 + $1.74 + $1.52 + $1.66) / 5
$8.05 / 5
$1.61
Hence, the mean price of today's loaf of bread at the five supermarkets is $1.61, choice D.
Alright, lets get started.
Yesterday's price of a loaf of bread are given = 1.44, 1.59, 1.69, 1.47, 1.61
Today each supermarket raised its price by 0.05.
Means new prices are :
1.44 + 0.05 = 1.49,
1.59 + 0.05 = 1.64,
1.69 + 0.05 = 1.74,
1.47 + 0.05 = 1.52,
1.61 + 0.05 = 1.66
Sum of new prices = 1.49 + 1.64 + 1.74 + 1.52 + 1.66 = 8.05
Means price of loaf of bread = sum of new prices / 5
Means price of loaf of bread = 8.05 / 5
Means price of loaf of bread = 1.61 $ : Answer
Hope it will help :)
