Kayla works at flower store.the owner tells kayla he wants to take 10 percent off a 18.00$ bouquet. If the bouquet still doesn’t sell the owner will again reduce the sale price by 15 percent. Kayla tells the owner the original price by 25 percent because the sale price would be the same

Respuesta :

Kayla is wrong because the calculation will give different amounts since one gave $13.77 while the other one was $13.50.

Taking 10% off and then 15% off will give a price that will be calculated thus:

= $18 - (10% × $18)

= $18 - $1.80

= $16.20

Taking 15% off will then be:

= $16.20 - (15% × $16.20)

= $16.20 - $2.43

= $13.77

Now taking 25% off directly firm $18.00 will give:

= $18.00 - (25% × $18.00)

= $18.00 - $4.50

= $13.50

Therefore, Kayla is wrong.
