Best ResponseYou've already chosen the best response.0Use the standard form of a line: Ax+By=C Let .01=value of the pennies Let .05=value of the nickels . (.01)(x)+ (.05)(450x)=14.50 .01x+22.50.05x=14.50 [Solve for x] .01x.05x=22.50+14.50 .04x=8 x=200 pennies 450200=250 nickels . Check by plugging the values back into the original equation: Ax+By=C (.01)(200)+(.05)(250)=$14.50 14.50=14.50 [Checks out]
