You have $18 to spend on oranges and grapes. Graph the equation 1.5x+2y=181.5x+2y=18, where xx is the number of pounds of oranges and yy is the number of pounds of grapes. Then find the maximum number of pounds of grapes you can buy.

Respuesta :

Answer:

Maximum number of pounds of grapes: 9

Step-by-step explanation:

If you spend all the money, $18, in grapes then you will maximize the number of pounds of grapes you can buy. That means, to solve the equation for y, the number of pounds of grapes, with x = 0 (the number of pounds of oranges):

1.5*0 + 2*y = 18

y = 18/2

y = 9
