Answer:
$1.8
Step-by-step explanation:
let x equal the money that she spend on the folders
let y equal the cost of 1 folder
let z equal the number of folders she bought
We got:
y + z = x
We know that :
y = 0.15
z = 12
So,
y * z = x
0.15 * 12 = x
1.8 = x
So x = 1.8
Alicia cost in total of $1.8 to buy folders
