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: 4 $3.60 $3.60(4) = $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.
