Answer:
checking account A is the better deal.
Step-by-step explanation:
A charges a monthly service fee = $12.00
Wire transfer fee = $10.50
B charges a monthly service fee = $21.00
Wire transfer fee = $8.50
If the requirement is four wire transfer per month
A charges for 4 wires = 10.50 × 4 = $42.00
and adding monthly service fees = 42.00 + 12.00 = $54.00
B charges for 4 wires = 8.50 × 4 = $34.00
and adding monthly service fees = 34.00 + 21.00 = $55.00
Therefore A charges less than B, so checking account A is the better deal.
Answer:
333.3 meters per minute
Step-by-step explanation:
<u>The best way to solve this problem is using </u><u>dimensional anaysis</u><u>. First, we write out our starting units, that being 20km/1hr. We have to keep in mind that we want to change the kilometers to meters and the hours to minutes.</u>
<u>We know that there are 1000 meters in 1 kilometer. We add this to the dimensional analysis as 1000m/1km. We write it as this because we want the kilometers to cancel each other out. We only want the meters.</u>
<u>We also know that 1 hour is 60 minutes. We add this to the analysis as well so that the hours cancel each other.</u>
<u>We now solve this expression. Since both the kilometers and the hours cancel out, we have meters per minute as our unit. All that's left are the numbers.</u>
= (20*1000*1)/(1*1*60) m/min
= 333.3 meters per minute
