Refer to the information above about the offer on lemonade brands. What combination of brands of lemonades would reduce the price even further? ( yes I only need part b) please show work

the answer is A. fordowne

fordowne is the least expensive brand to buy because it is 31.25 and the rest of the deals all come to a cost of 33 dollars.

2 dollars off when three 2 liter bottles are purchased. - fordowne.

2.75x3 is 8.25 - 2 is 6.25

6.25 for 6 liters

6 times 5 is 30

so 6.25 times 5 is 31.25

the lowest deal

if you want any other explanations i'll be happy to give them to you

Question 3:

50-3n=5

therefore,

50-5=3n

45=3n

n=45/3

n=15

The 15th term of the sequence has a value of 5.

sorry i am not sure about the rest, i am new to this topic and have just started learning it.
