Answer:
y = - 8
Step-by-step explanation:
y - 16 - 3y = 0
Group like terms
y - 3y - 16 = 0
Add similar elements: y - 3y = - 2y
- 2y - 16 = 0
Add 16 to both sides
- 2y - 16 + 16 = 0 + 16
Simplify
- 2y = 16
Divide both sides by - 2
=
Simplify : y
Apply the fraction rule:
=
Divide the numbers:
= y
Simplify : - 8
Apply the fraction rule:
Divide the numbers: = 8
= - 8
y = - 8

Answer:
The difference between buying online and buying in store is $12.50. The difference between the markups themselves is $2.50. Because the markup of buying in store is more than buying online, we can tell that buying in store costs more than buying online.
Step-by-step explanation:
The markup of buying online is $40 (25% of 160). Because of this, we'll add $40 to the original price, which means that buying online would cost you $200. On the other hand, the markup of buying in a store is $52.50 (35% of $160). This means we'll add $52.50 to the original price, giving us a total of $212.50. We now know that buying at the superstore costs $212.50, and buying online costs $200. To find the difference, we subtract $200 from $212.50. We get $12.50, which means that <u>the difference in total price is $12.50.</u>
Next, we're trying to find out the difference between the markups themselves. Since we know that the markup of buying online is $40, and the markup of buying in store is $52.50, we have to subtract $40 from $52.50. We are left with $2.50. Therefore, <u>the difference between the markups is $2.50.</u>
We can draw the conclusion that because the markup price for buying in store is more than the markup price of buying online even though they (without markup) cost $160, it'll cost more in store.
