Crabberry juice costs $6.30 per quart and apple juice costs$3.60 per quart. Terrence wants to make a mixture of apple and cranberry juice that sells for $4.50 per quart. How many quarts of q of cranberry juice should he mix with 4 quarts of apple juice to make cranberry- apple juice at that price? which equation below represents the situation?

• 3.6(q-4)+25.2= 4.5q

• 3.60q+25.20 = 4.50(q+4)

• 6.30(q-4)+14.40= 4.50q

• 6.30q +14.40 = 4.50(q+4)
