Dave bought 18 packets of cookies for $19.80. each packet of cookies contains 10 cookies. find the cost of each cookie to the nearest tenth of a cent.

There are 18 packets.

Each packet has 10 cookies.

Let T = total number of cookies.

T = 10(18)

T = 180

There are 180 cookies.

Let C = cost of each cookie.

Use the equation C = 19.80/T.

You know what T is, right? Look above to see the value of T. Plug that T-value into the equation and solve for C.

After that, round your answer as instructed.

set each factor equal to 0

4x-3 = 0

2x-1 = 0

solve for x.

4x-3=0

4x=3

x= 3/4

solve for x. 

2x-1= 0

2x= 1

x= 1/2

your answer should be 1/2 is less than or equal to x and 3/4 is greater than or equal to x
