Explanation Given: A public radio station offers two levels of support during a fundraiser. Level 1 membership requires a $25 donation and Level 2 membership requires a $50 donation. At the end of the day, a fundraiser had pledges for $350. Formula Used: Linear Equation: ax+by=c Calculation: The above given problem can have more than one solution and can be stated in the form of a linear equation as; Let the equation be : ax+by=c where, a=Level 1 membership donation=$25 b=Level 2 membership donation=$50 c=total donation collected=$350 x=number of Level 1 pledges y=number of Level 2 pledges Thus, the equation can be written as: 25x+50y=350 Now, this equation can be solved by taking y = 0,1,2,3,4,5,6 and 7 and getting the corresponding values of x. We have taken all the positiveinteger values of y starting from 0 to 7 as long as x is not negative. As a value of y greater than 7 would end up giving a negative value of x which is also not possible as number of pledges received cannot be a negative value or fractional value...
