Im confused lol. its late and i wanna go to sleep lol

Total: $264

School: $192

Homeroom: $72

Step-by-step explanation:

Simply multiply 11 * 24 because, it is $11 for one coupon book. And, he sold 24.

Then, multiply 8 * 24 because, the school gets $8 for one coupon book. And he sold 24.

Finnaly multiply 8 * 3 because, the homeroom gets $3 for one coupon book. And he sold 24.

Hope this helps :-)

i think it would be 42cm

step-by-step explanation:

to find if any function is an inverse of the other, put the first equation in as x in the next one. then simplify and solve. if at the end you get the statement y = x, then it is an inverse. if you get anything else, it is not.
