Let us assume that cost of each granola bar be $x and that of a cup of yogurt be $y
From person A's purchase, we get
12x + 7y = 15.5; equation A
And from person B's purchase,
6x + 11y = 11.5; equation B
Let us multiply equation B by 2 and subtracting equation A from it, we will get
12x + 22y - 12x - 7y = 23 - 15.5,
=> 15y = 7.5
or, y = 0.5
Substituting value of y in equation A, we can find x
12x + 7*0.5 = 15.5
=> x = (15.5 - 3.5)/12
or, x = 1
Therefore, cost of granola bar is $1, and that of yogurt is $0.5

Quick Note: I'm pretty sure you meant 180LBS and not 1801bs, so I'm using 180, but if it was 1801 please tell me
Percent of change =

Substitute 180 for V2 and 160 for V1
Percent of change =

Solve
Percent of change =

Percent of change = 0.125 x 100
Percent of change = 12.5%
Answer: 1747067797/2500000000
Step-by-step explanation:
Rewrite the decimal number as a fraction with 1 in the denominator
0.6988271188=0.6988271188/1
Multiply to remove 10 decimal places. Here, you multiply top and bottom by 10 to the 10 power = 10000000000
0.6988271188/1 * 10000000000/10000000000 * 6988271188/10000000000
