cranberry juice cost $6.30 per quart and apple juice cost $3.60 per quart Terence wants to know how many quarts q of cranberry j
Gekata [30.6K]

Note: "total" is from adding the first and last columns (middle column should be provided because it is a rate which cannot be added).

                       Amount        x        Cost             =         Amount x Cost

Cranberry:          q                        $6.30                          $6.30q

Apple:            <u>    4       </u>                  <u>$3.60</u>                      <u> $3.60(4)  = $14.40</u>

Total:                4 + q                     $4.50           =         $6.30q + $14.40

                                                   $4.50(4 + q)   =          $6.30q + $14.40

                                             $18.00 + $4.50q  =          $6.30q + $14.40

                                                              $3.60  =           $1.80q

                                                                    2    =           q

Since you didn't provide the equation options, hopefully you can use the solution to help you decide which option to choose.
