Sum of a finite geometric series:

Does anyone knows the answer to this? Pls

im pretty sure it would be 5 am, hope that , and give brainliest and guys if this is right then press the button and give 5 stars

step-by-step explanation:

well if you round, things become much more simple. round 5.95 to 6, 4.25 to 4, and 1.05 to 1. now, add 6+4+1 and that would equal 11. so the items together would equal to about $11.
