Question

What’s the percent from $18 to $45

Answer 1

When finding a percent, you must do a strategy called FOO ( final minus original divided by original)
The original is the first number and the final is the second
After FOO you multiply the answer by 100 to make it a precent
The equation looks like this
45-18÷18×100
This equals 150%

Answer 2

Is would be a 150% increase. Since your going from 18 to 45, your increase of percentage would be 150%, and the difference is 27.
