Question

the cheese that ms.carter used to buy costs $6.00 per pound, but it's been marked up 15%. how much did it cost her to buy 2.6 pounds of cheese at the old price?

Answer 1

The cost to buy 2.6 pounds of cheese at the old price was $13.565217...

Step-by-step explanation

Lets assume, the old price of the cheese is
`x` dollar per pound

Now it is marked up by 15%, so the marked up amount will be: 15% of
`x`
`= 0.15x`

So, the new price of the cheese
`=(x+0.15x)= 1.15x` dollar per pound, which is also given as $6.00 per pound

Then ,
`1.15x = 6.00 \\ \\ x = (6.00)/(1.15)= 5.217391....`

Thus, the old price of the cheese is $ 5.217391... per pound

So, the cost to buy 2.6 pounds of cheese at the old price
`= (5.217391... *2.6) =13.565217...dollar`
