Answer:
$4.73
Step-by-step explanation:
We can solve this problem using proportion. If 120 tablets cost $8.73, then we can set up a proportion to find out the cost of 65 tablets:
120 tablets / $8.73 = 65 tablets / x
where x is the cost of 65 tablets.To solve for x, we can cross-multiply:
120 tablets * x = 65 tablets * $8.73
Simplifying:
x = (65 tablets * $8.73) / 120 tabletsx = $4.73
Therefore, the cost of 65 tablets is $4.73.
To check the solution, we can use the given information that 120 tablets cost $8.73. We can find the cost per tablet by dividing the total cost by the number of tablets:
Cost per tablet = Total cost / Number of tabletsCost per tablet = $8.73 / 120 tablets
Cost per tablet = $0.07275 (rounded to five decimal places)
Now, we can use the cost per tablet to find the cost of 65 tablets:
Cost of 65 tablets = Number of tablets * Cost per tablet
Cost of 65 tablets = 65 tablets * $0.07275
Cost of 65 tablets = $4.72375 (rounded to five decimal places)
Therefore, the cost of 65 tablets is $4.73 (rounded to two decimal places).
