During the fall, the deli counter in a grocery store offers a rice blend made of wild rice costing

Zinaida [17]

If an employee has already measured out 59 pounds of wild rice. The number of pounds of long grain brown rice should she add to make the blend is: 88.5 pounds of long grain.

<h3>Number of pounds of long grain</h3>

Let x represent number of pounds of long grain

6.45×59+3.95x=(59+x)×4.95

380.55+3.95x =292.05+4.95x

380.55–x =292.05

-x=292.05-380.55

-x = -88.5

x = 88.5 pounds of long grain

6.45×59+3.95x=(59+x)×4.95

x=(6.45-4.95)×59

x=1.5×59

x=88.5 pounds of long grain

Therefore If an employee has already measured out 59 pounds of wild rice. The number of pounds of long grain brown rice should she add to make the blend is: 88.5 pounds of long grain.
