The Number of people who became members in month, x = 5 are 76

The equation given represents a linear expression representing :

x = total number of people who became members that month

To obtain the number of people who became members in a particular month, we input the value of x into the equation and calculate the output :

For instance, if Number of month, x = 5

The Number of people who became members is :

y = 0.8(5) + 72

y = 4 + 72

y = 76

Hence, the Number of people who became members in month, x = 4 are 76
