6. a store charges $4.80 for 16 ounces of bubble tea. complete the table so that it shows a proportional relationship between ounces of tea and cost.
Answer
Explanation:
Step1: Find the unit rate
The unit rate ( r) (cost per ounce) is calculated by dividing the cost by the number of ounces. Given (16) ounces cost (4.80) dollars, so (r=\frac{4.80}{16}). [r = 0.3]
Step2: Find the cost for (20) ounces
Using the formula (y = rx) (where (y) is the cost and (x) is the number of ounces), when (x = 20) and (r=0.3), we have (y=0.3\times20). [y = 6]
Step3: Find the number of ounces for a cost of (7.20)
Using the formula (x=\frac{y}{r}), when (y = 7.20) and (r = 0.3), we have (x=\frac{7.20}{0.3}). [x=24]
Answer:
For (20) ounces, the cost is (6) dollars. For a cost of (7.20) dollars, the number of ounces is (24).
