Matt owns a lawn mowing and landscaping business. The income from the business is given by the function f(x) = 2x + 54, where f(x) is the income in dollars and x is the area in square meters of lawn mowed. If Matt has earned {204, 344, 450, 482} dollars in the last four months, what are the corresponding areas of lawn he mowed? {75, 145, 198, 214} {84, 123, 204, 254} {70, 135, 184, 195} {80, 110, 185, 246} {95, 148, 175, 206}

Respuesta :

plug in 204 for f(x) and solve for x
204 = 2x + 54
150 = 2x

x = 75 sq ms

344 dollars:-

344 = 2x + 54
2x = 290
x = 145 sq ms
