Answer 2

Michael bought a venti vanilla frappe from Starbucks, which was 20 oz. Percentage of drink left is 65 %

Solution:

Given that Michael bought a vanilla frappe which is 20 oz

He drank away 7 oz

To find the percentage of his drink which is left:

Amount of drink left = Total quantity of drink - quantity of drink which was drank by Michael

Amount of drink left = 20 - 7 = 13 oz

Now percentage of drink left over is found by dividing the amount of drink left by total amount of quantity and multiplied by 100

`\text { percentage of drink left over }=\frac{\text { quantity of drink which is already drank }}{\text { total quantity of drink }} * 100`

Percentage of drink left over
`= (13)/(20) * 100\\\\ = 13 * 5 = 65 \%`
