Aloiza [94]

Answer:

50 and 30.94

Step-by-step explanation:

  • a

The coat cost 46.5 pounds after a 7 percent reduction

so we can write:

  • 46.5⇒ (100-7)⇒ 93 percent
  • x(the initial price) ⇒ 100 percent

using the proprtionality relation:

x= (100*46.5)/93 = 50

so the initial price of the coat is 50 pounds

  • b

The jumper costs 32.8 pounds after an increase of 6 percent

so:

  • 32.8⇒(100+6)⇒ 106 percent
  • x (the initial price)⇒ 100 percent

using proportionality:

x= (100*32.8)/106 = 30.94

the initial price is 30.94 pounds
