Answer:
Amount each friend pays for the gift = $20
Step-by-step explanation:
Market price of a gift = $70
The store manager takes $10 off the market price.
Marked down amount = $10
New cost price = Marked price - Marked down amount
The cost of the gift is divided among three friends.
This means that the cost of gift which is $60 is divided by three to get each one's contribution in the gift.
∴ Amount each friend pays for the gift
Answer:
No
Step-by-step explanation:
For x and y to have a proportional relationship, then
the ratio of k = must be equal for all points
(2, 5) → k = = 2.5
(3, 7.5) → k = = 2.5
(5, 12.5) → k = = 2.5
(18, 8) → k = = 2.25 ≠ 2.5
k is not equal for all values , hence no proportional relationship exists
