Use the unit rate of $2.09 per pound to find the cost of 8.5 pounds of grapes. [type your answer as a number and round to the nearest cent.] 8.5 pounds of grapes = $

multiply total weight by unit cost

8.8 x 2.09 = 17.765 = $17.77

The first answer is

Formula for direct function is f(x)=a*x

When we replace f(x)=56 and x=8 we get

8*a=56 => a=56/8=7     a=7

When we replace a=7 in the unknown function we get

f(x)= 7*2=14

The second answer is

Function which is not direct is y=9/x

Good luck!!!
