Which equation shows how many cookies she had left for the party?

1 point
20 + 16 - 22 = c
20 x 16 - 22 = c
20 x 16 - 20 x 22 = c
20 + 16 x 22 = c
1. 20 x 16 - 22 = c
To figure out how many cookies Jan had left for the party, we need to subtract the cookies that broke from the total number of cookies she baked.
Jan baked 20 trays of cookies, and each tray had 16 cookies on it. So the total number of cookies she baked is 20 x 16 = 320 cookies.
She threw away 22 cookies that broke. Therefore, we need to subtract 22 from 320 to find out how many cookies she had left.
The equation that represents this is:
320 - 22 = c
So the correct equation is:
20 x 16 - 22 = c
Correct!
20 trays x 16 cookies per tray = 320 cookies
320 cookies - 22 broken cookies = 298 cookies left for the party.
