Question

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

Answer 1

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

Answer:

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
