The answer is c = 3r. Note that c is the output and r is the input. I figured this out by using mental math and noticing the pattern. Each value the input is multiplied by 3, which results in the output.

(INPUT)2 * 3 = 6 (OUTPUT)
(INPUT)4 * 3 = 12 (OUTPUT)
(INPUT)7 * 3 = 21 (OUTPUT)
(INPUT)10 * 3 = 30 (OUTPUT)
(INPUT)12 * 3 = 36 (OUTPUT)

Anna has made 30 chocolate chip cookies and 54 sugar cookies. She wants to put them in bags for her friends with the same number
NARA [144]

Answer:

Therefore the greatest number of cookies she can put each bag is 14.

Step-by-step explanation:

Given that Anna has made 30 chocolate chip cookies and 54 sugar cookies.

First we have to find out the number of fried or the number of bags.

So to find the number of bags, We need to find out the G.C.D of 30 and 54.

30=5×3×2

54=3×3×3×2

The common divisor of 30 and 54 is = 3×2 = 6

∴The  G.C.D of 30 and 54 is 6.

The number of bags is 6.

The number of chocolate cookies each bags is

=(The number of chocolate cookies÷ 6)

=30÷6

=5

The number of sugar cookies each bags is

=(The number of sugar cookies÷ 6)

=54÷6

=9

Therefore the greatest number of cookies she can put each bag is (5+9)=14.
