Question

Plz help meeeeeee and plz show the work I have been stuck on this for hours

Answer 1

Bryson bought
`2(3)/(4)` pounds of veggie burgers for $8.80.

Part A) What is the unit price per pound of the veggie burgers? Show your work

Answer:

Total pounds of veggie burgers
`=2(3)/(4)=(11)/(4)`

Cost of
`2(3)/(4)` pounds of burgers = $8.80

The unit price per pound of the veggie burgers:

`=8.80\:/ (11)/(4)`

`=(8.8)/(1)/ (11)/(4)`

`\mathrm{Apply\:rule}\:(a)/(1)=a`

`=8.8* (4)/(11)`

`=(4* \:8.8)/(11)`

`=(35.2)/(11)`

`=3.2`

Therefore, the unit price per pound of the veggie burgers: $3.2

Part B) There are 16 ounces in a pound. What is the unit price ounce of the veggie burgers.

Total pounds of veggie burgers
`=2(3)/(4)=(11)/(4)`

Cost of
`2(3)/(4)` pounds of burgers = $8.80

Total number of ounces in a pound = 16

Total number of ounces in
`2(3)/(4)` pounds
`=(11)/(4)* \:16=44`

The unit price per ounce of the veggie burgers:

`=(8.8)/(44)`

`=0.2`

Therefore, the unit price per pound of the veggie burgers: $0.2

Part C) At that unit price, what is the price for
`4(1)/(2)` pounds of veggie burgers? Show your work.

As the unit price per pound of the veggie burgers: $3.2

The price for
`4(1)/(2)` pounds of veggie burgers:

`=4(1)/(2)* 3.2`

`\mathrm{Convert\:mixed\:numbers\:to\:improper\:fractions}:\quad 4(1)/(2)=(9)/(2)`

`=(9)/(2)* \:3.2`

`\mathrm{Multiply\:fractions}:\quad \:a* (b)/(c)=(a\:* \:b)/(c)`

`=(9* \:3.2)/(2)`

`=(28.8)/(2)`

`=14.4`

Therefore, the price for
`4(1)/(2)` pounds of veggie burgers will be: $14.4
