Asocial networking site recorded that 80 per-cent of people who became members of the site one month were between 30 and 40 years old the equation below represents information where x represents the total number of people who became members of the site that monthx=0.8x +72how many people who became members of the site that wants where between 30 and 4 years of age

x=360          30-40 yrs =288

Step-by-step explanation:

multiple 72 by .05 (36) to find 10 percent, then multiple 80 percent by that number(36) then add both numbers together to get total number of members that month

(72x.05)=36x2+(.80x36)=288

288+72=360

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

The equation given represents a linear expression representing :

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
