3 friends share the cost of a gift. The gift costs $70, but the store manager takes $10 off the market price. What amount should
My name is Ann [436]

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 =\$70-\$10=\$60

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 =\frac{60}{3}=\$20
