$0.29 * 3 = $0.87
$0.98 * 2 = $1.96
$1.39 * 1 = $1.39
0.87 + 1.96 = 2.83
2.83 + 1.39 = 4.22
10.00 - 4.22 = $5.78
she will get $5.78 back!
I believe the difference is where it is made ^^
maggi is made in India and pasta is made in Italy
they may also have different sauces and spices used which also helps differ between the two :3
All of the above is the right one
First you would need to move the variable causing it to change its sign
5x=10-y
Then divide both sides by 5
X=2-1/5y
Then you are left with your answer:
x=2-1/5y
Hope this helps! :3
