Question

9.) Apples cost $0.89 per lb. If your friend wanted a 5.2 lb bag of apples, but you wanted a six and five tenths pound bag, how much would you pay alone? ​

Answer 1

Cost of apples per lb = $0.89

Weight of apples my friend wants = 5.2 lb

Price my friend has to pay =

`= 5.2 * 0.89`

`= $4.628`

My friend has to pay $4.628 .

Quantity of apple I want =

`= 6 (5)/(10) \: pounds`

Price I have to pay :-

`= 6 (5)/(10) * 5.2`

`5.2 = (5 * 5)/(2 * 5)`

`5.2 = (25)/(10)`

`= 6 (5)/(10) * (25)/(10)`

`= ((10 * 6 + 5))/(10) * (25)/(10)`

`= (65)/(10) * (25)/(10)`

`= (65 * 25)/(10 * 10)`

`= (1625)/(100)`

`= $16.25`

Therefore , I alone would have to pay $16.25 .
