The ratio of selling price to cost price is. 3.65 : 1.72
The cost price is 28.50 and you want to find the selling price so let x replace that spot
x : 28.50
cross multiply 3.65 × 28.50 and 1.72 × x
3.65 × 28.50 = 104.025
1.72 × x = 1.72x
104.025 = 1.72x
x is approximately $60.48
Let's subtract then: 3x2 - 2x + 3 - (6x2 - 4x + 3)
taking out of the bracket with a changed sign: (there is a minus in front of the bracket)
3x2 - 2x + 3 - 6x2 + 4x - 3
let's reshuffle them so that similar terms are together:
3x2 - 6x2 - 2x + 4x + 3 - 3
Adding up similar terms:
-3x2 + 2x - that's our option 2!
