The owner of a small store buys coats for 50.00$ each. a .she sells the coats for 90.00 each. what percent of the purchase price is the selling price? b. the owner increases the sale price the same percent that you found in part a when she buys jackets for $35 and sells them. how many jackets must the owner buy for the total jacket sales to be at least $250? explain your answer.

Step-by-step explanation:

A)The owner of a small store buys coats for 50.00$ each. She sells the coats for 90.00 each.

Profit = selling price - cost price

Profit = 90-50 = $40

percent of the purchase price is the selling price will be

Purchase or cost price/selling price × 100

= 50/90 ×100 = 55.56%

B) she buys jackets for $35 and sells them. The owner increases the sale price the same percent as in part A.

This means

Cost price /selling price × 100 = 55.56

35/selling price × 100 = 55.56

35×100 = 55.56 × selling price

Selling price = 3500/55.56 = 62.99

To find the number of jackets that the owner must buy for the total jacket sales to be at least $250,it becomes

250/62.99 = 3.96

The Least number of jackets jackets is 4. She cannot buy 3.96 jackets because it must be whole. If he buys 3 jackets, he would make lesser than $250

it has the same slope and a different y-intercept

hope this : )
