Bryson bought $2\frac{3}{4}$ pounds of veggie burgers for $8.80.Part A) What is the unit price per pound of the veggie burgers? Show your work

Total pounds of veggie burgers $=2\frac{3}{4}=\frac{11}{4}$

Cost of $2\frac{3}{4}$ pounds of burgers = $8.80

The unit price per pound of the veggie burgers:

$=8.80\:\div \frac{11}{4}$

$=\frac{8.8}{1}\div \frac{11}{4}$

$\mathrm{Apply\:rule}\:\frac{a}{1}=a$

$=8.8\times \frac{4}{11}$

$=\frac{4\times \:8.8}{11}$

$=\frac{35.2}{11}$

=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 $=2\frac{3}{4}=\frac{11}{4}$

Cost of $2\frac{3}{4}$ pounds of burgers = $8.80

Total number of ounces in a pound = 16

Total number of ounces in $2\frac{3}{4}$ pounds $=\frac{11}{4}\times \:16=44$

The unit price per ounce of the veggie burgers:

$=\frac{8.8}{44}$

=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 $4\frac{1}{2}$ pounds of veggie burgers? Show your work.

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

The price for $4\frac{1}{2}$ pounds of veggie burgers:

$=4\frac{1}{2}\times 3.2$

$\mathrm{Convert\:mixed\:numbers\:to\:improper\:fractions}:\quad 4\frac{1}{2}=\frac{9}{2}$

$=\frac{9}{2}\times \:3.2$

$\mathrm{Multiply\:fractions}:\quad \:a\times \frac{b}{c}=\frac{a\:\times \:b}{c}$

$=\frac{9\times \:3.2}{2}$

$=\frac{28.8}{2}$

=14.4

Therefore, the price for $4\frac{1}{2}$ pounds of veggie burgers will be: $14.4
