Final answer:
After dividing $18.99 by 220 the result is approximately 0.08631363636. When rounded to the nearest cent, it becomes $0.09.
Step-by-step explanation:
To evaluate $18.99 divided by 220 and round to the nearest cent, we need to perform a division operation. the division yields a result which may have many decimal places but when we are rounding to the nearest cent we are interested in keeping only two decimal places as a cent is 1/100th of a dollar. first, divide $18.99 by 220: $$\frac{18.99}{220} \approx 0.08631363636...$$
Now, to round this number to the nearest cent, we will look at the third decimal place. if it is 5 or more we round up. if it is less than 5, we round down. here, the third decimal place is 3, which is less than 5. therefore, we round down, and the result is: $$0.08631363636... \approx 0.086 (to the nearest cent)$$
Expressed in dollar format, the final rounded result is $0.09.
