Answer:you would have saved $31 after 5 days
Step-by-step explanation:
You double the number of dollars in the envelopes from the day before. This means the amount in a day is double the amount in the previous day. Therefore, amount of money in the envelope is increasing in geometric progression. The formula for determining the sum of n terms of a geometric sequence is expressed as
Sn = a(r^n - 1)/r - 1
Where
a represents the first term.
r represents the common ratio.
From the information given,
a = 1
r = 2
n = 5 days
S5 = 1(2^5 - 1)/2 - 1
S5 = 32 - 1 = 31
Answer: 12 pints
Step-by-step explanation: if there are 8 pints in a gallon. We have 1 and 1/2 gallons
1 gal = 8 pints
1/2 gal = 4 pints
8 + 4 = 12 pints total
Answer:
-21
Step-by-step explanation:
Basically all you have to do is plug in numbers for Y and C. the formula is (y,x) so use numbers like (1,3) and as long as it fits in the equation (the equation ends up true. like in this case (1 < 2) which means it worked) you can graph that point.
