Devon paid for 4 pounds of bananas with a $10 bill. he got back $4.00. what was the cost of 1 pound of bananas? $3.50 $24.00 $1.50 $1.00

see explanation

step-by-step explanation:

since the sequence is geometric there is a common ratio r between consecutive terms, that is

r = 4 ÷ - 2 = - 2

r = - 8 ÷ 4 = - 2

r = 16 ÷ 8 = - 2

the next term - 13 must be incorrect as it should be - 32 for the sequence to be geometric.

the first 4 terms are therefore geometric with common ratio r = - 2

the correct answer is you spend $55.78 more in a brand store that buy ing in a normal store.

step-by-step explanation:

brand = spend   $ 135.85 total

store = spend $80.07 total

you can first factor out the n to get n(1+5). we know that 1+5 is 6, so we just have 6n.
