Step 1: Let's first make a list of what is given in the question.
No. of concerts where Victor played guitar this month = 8 concerts
No. of hours each concert lasted = 2.75 hours
Step 2: Let's generate the expression.
The number of hours Victor played in the concert is equal to the number of concerts he participated in multiplied by the number of hours the concert lasted.
Let,
y = number of hours Victor played in the concerts
x = number of concert
k = standard number of hours each concert lasted
We get,
y = kx or y = 2.75x
Step 3: Let's determine how many hours Victor played the guitar in the concerts.
x = 8 concerts
k = each concert lasted 2.75 hours
y = to be determined
y = (2.75)(8)
y = 22 hours
Therefore, Victor played a total of 22 hours in the concerts.
