Svetach [21]
What we know:
Petrolyn motor oil is a combination of natural oil and synthetic oil. It contains 7 liters of natural oil for every 5 liters of synthetic oil.

What we need to find:
If 355 liters of synthetic oil are used, how many liters of petrolyn oil will be made?

Set up a proportion to find how much natural oil is used.
7L natural oil/5L synthetic oil = x/355 synthetic oil where x=natural oil
7/5=x/355
(5)(x)=(7)(355) cross multiplied
5x=2485 simplified
5/5x=2485/5 multiplicative inverse
x=497L

Now, add both synthetic oil and natural oil to find amount of petrolyn oil.

355 L synthetic oil + 497 L natural oil= 852 L of petrolyn oil

Answer:

  £592 for 16 boxes

Step-by-step explanation:

The classroom floor area is ...

  A = LW = (8.8 m)(2.2 m) = 19.36 m²

The cupboard floor area is ...

  A = (2.3 m)(2.1 m) = 4.83 m²

Then the total area to be covered is ...

  19.36 m² +4.83 m² = 24.19 m²

At 1.6 m² per box, the number of boxes required is ...

  (24.19 m²)/(1.6 m²/box) = 15.12 boxes

If we assume we can only purchase whole boxes, we need to purchase 16 boxes to cover the floor. The cost will be ...

  (16 boxes)(£37/box) = £592 . . . . cost of laminate to replace the floor
