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: Â Â Â Â Â Â Â Â 4 Â Â Â Â Â Â Â Â Â Â Â Â $3.60 Â Â Â Â Â Â Â Â Â Â Â $3.60(4) Â = $14.40
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.
Answer:
6.30 q + 14.4 = 4.50 ( q + 4 )
Step-by-step explanation:
Here, q quarts of cranberry juice is mixed with 4 quarts of apple juice,
So, the quantity of total juice = ( q + 4 ) quarts,
Also, the price of cranberry juice is $6.30 per quart and the price of apple juice is $ 3.60 per quart while the price of resultant mixture is $ 4.50 per quarts,
⇒ 6.30 × q + 3.60 × 4 = 4.50 × total quantity of resultant mixture
( ∵ Total cost = cost of per unit × number of units )
⇒ 6.30 q + 14.4 = 4.50 ( q + 4 )
Which is the required equation.
