Ally and Robert went up a hill to fetch water. Robert fetched 2 pails and Ally got 8. If Robert fetched 24 fewer pails than ally over a week, how many pails did jack fetch?

Ally fetched 32 pails and Robert fetched 8 pails

Step-by-step explanation:

If Robert fetched 2 pails and Ally fetched 8 pails, Ally fetched 4 times as many as Robert.

So  4R = A  (where R = number of pails Robert fetched and A = number of pails Ally fetched)

If Robert fetched 24 fewer pails than Ally:

R = A - 24

Assuming you want to know how many pails ROBERT fetched:

Substitute R = A - 24  into  4R = A:

4(A - 24) = A

 4A - 96 = A

        3A = 96

          A = 32  (so Ally fetched 32 pails)

Now substitute the found value for A into R = A - 24 to find number of pails ROBERT fetched:

R = A - 24

  = 32 - 24

  = 8

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

x = 23.78
