Anna buys 5lb of pecans for $19. At this unit rate, find the cost of the following amounts. 1/2, 3

1/2 lb of pecans would cost $1.9

3 lbs of pecans would cost $11.4

Step-by-step explanation:

The rate given is 5 lb of pecans for $19

FIND THE UNIT RATE OF DOLLARS PER POUND OF PECANS BY:

19 ÷ 5 = 3.8

THE UNIT RATE IS $3.8 per pound of pecans.

Use unit rate to determine how much will the following amounts of pecans cost:

1/2 lbs

1/2 x 3.8 = $1.9

3 lbs

3 x 3.8 = $11.4

choice b is correct
