Protein smoothie =14

Berry Smoothie= 29

Step-by-step explanation:

Let number of protein smoothie be X

Let number of berry smoothie be Y

1. X+Y=43

Y=43-X

2. 10X+6Y=314

5X+3Y= 157

5x+3(43-x)=157 (substitute)

5x+129-3x=157

2x=157-129

x=14

X+Y=43

Y=43-14

Y=29

The total cost of shipping a package with the cost of $15 exclusive if 5% insurance is 15.75 dollars. This is calculate by getting first the 5% of 15 dollars, 15 dollars multiplied by 5%, equal to 0.75 dollars. Then it will be added to the shipping cost of 15, which is equal to 15.75 dollars.
