There are 128 ounces in 1 gallon
1,5gallons= 192 ounces
Scott = 3 oz per lid
192 divided by 3 = 64 lids of detergent
Nikki = 4oz per lid
192 divided by 4 = 48 1/2 lids
64 - 48.5 = 15.5 lids more
Step-by-step explanation:
The answer is 12 because 4^2 is 16 minus 4 is 12
A(n)=4+4(n-1)
a(n)=4+4n-4
a(n)=4n
76=4n
n=19
The sum of any arithmetic sequence (series are infinite) is:
(a+a(n))(n/2)
The average of the first and last terms times the number of terms, in this case we found that n=19 so:
19(4+76)/2=760
