It will take Alexis 5 weeks. If she starts off with $50, she will still need $150. Then, she earns $30 each week every week. Making $30 for 5 weeks will get Alexis to $150, because 30×5 is 150. Then once you add in the money she started with you will get $200. $150+$50=$200.
Answer:
This is a convergent geometric series. The sum is 30.
Step-by-step explanation:
In your series, the ratio of terms is 3/5, a value whose magnitude is less than 1. That means the series is convergent. The sum is given by the formula ...
S = a1/(1 -r)
where a1 is the first term (12) and r is the common ratio (3/5). This gives ...
S = 12/(1 -3/5) = 12·5/2 = 30
The series is convergent and has a sum of 30.
$1.60 = 1/2 a pound
$1.60 x 2 = 1 pound
$3.20 = 1 pound
$64.00 / $3.20 = 20 pounds
You can buy 20 pounds of grapes for $64.00 .
D is your answer because you add all the prices and multiply them by .072 then add that number to all the amounts added together
