Rebecca is comparing two prices of peanut butter. Peanut butter A has 12 ounces and
costs $6.00. Peanut butter B has 32 ounces and
costs $18.00. Which one is a better buy?

Peanut butter A is the better buy,

Step-by-step explanation:

To compare them directly, we can find the price per ounce for each peanut butter.

Peanut butter A has 12 ounces and costs $6, thus, each ounce is

Peanut butter B has 32 ounces and costs $18, thus, each once is

Therefore, Peanut butter A is the better buy.

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
