Part A.
Before you can write any sort of expression, you need to define variables. "grapes g" is not a definition, so the exercise seems meaningless as written. It seems the intent is to ...
let g, b, p represent the numbers of pounds of grapes, bananas, and pears, respectively.
Then, the total cost of some weight of fruit is
2.19g + 0.59b + 1.49p
Part B.
For g=3, b=3, p=2, the expression evaluates to
2.19*3 +0.59*3 +1.49*2 = 11.32
The total cost of 3 pounds of grapes, 3 pounds of bananas, and 2 pounds of pears is ...
$11.32

Lastly, I added 11.20 to 5.60 and got 16.80, and subtracted 16.80 from 30 and got 13.20.....
Answer:
x = 4
Step-by-step explanation:
You want x when ...
g(x) = f(2)
2x -3 = 3(2) -1
2x = 8 . . . . . . . . add 3, simplify
x = 4 . . . . . . . . . divide by 2
Answer:
z =2.76
Step-by-step explanation:
z - 2.3 = 0.46
Add 2.3 to each side
z - 2.3+2.3 = 0.46+2.3
z =2.76
