through my calculations x=8
OK so for substitution you will be taking away so say you have 5 apples and someone eats 3 you now have 2 apples. so it would be 5 - 3 =2
I hope this helps
Step-by-step explanation:
"markup" contains "up". so, the price goes "up". this is actually increasing the price (e.g. by calculating the profit margin of selling an item on top of the cost of buying the item from the manufacturer).
"markdown" contains "down". so, the price goes "down". e.g. with discounts.
here we have a markup. it is 150%.
that means the price goes up by 150% compared to the original cost.
so, the computer game costs in the store
the original cost + 1.5× original costs
25 + 1.5×25 = 2.5×25 = $62.50
