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 :-)

the least common denominator is 40

rounding to the nearest thousandth would be 452,000
