Answer:

one plain cookie costs $0.50

Step-by-step explanation:

so 25 x 6 is the extra cost

150 cents is the extra cost

subtract that from 9.50

you are left with $8

now we know that 16 plan cookies cost $8

so one plain cookie costs $0.50

Answer:

.50c

Step-by-step explanation:

1) You take the cost of the extra cookies and subtract from the total so 6 * .25 = 1.50 then 9.50 - 1.50 = 8.00

2) you take the 8.00 then divide it by the total number of cookies which is 8.00 ÷ 16 = 0.50
