Mathematics
1 answer:
inessss [21]3 years ago

Answer:

D. 10.5h-30=138

Step-by-step explanation:

I got you bro:

Lonnie is wrong. He forgot to multiply 10.5 by h, or the number of haircuts Rhonda gave. It doesn't make sense that she only gave 1 haircut. Also, he added 30, when since she is being charged, should be subtracted from the amount of money she made, or 10.5h.

Don't make the same mistake! Multiply 10.5 by h and  subtract 30! Your correct answer would be d.

Hope this helps!
