Tina and her friend are picking apples at Newberry Orchard. The apples cost $1.40 per pound. If they pick 2.5 pounds of apples, how much will the apples cost?

$3.50

Step-by-step explanation:

the apples cost $1.40 per pound, so if we have 2.5 pounds, we would need to do this:

1.40 × 2.5

3.5

I hope this helps!

28

step-by-step explanation:

8+8+6+6

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
