Answer:

C. 1.15x because adding 15% to the cost of the haircut is the same as multiplying the cost by 1.15.

Step-by-step explanation:

This answer is correct because, adding 0.15x (or 15%) to the total amount is the same as multiplying the cost by 1.15. This is because, the 1 that is added to 0.15 represents the total, since we are just multiplying instead of adding to it.

Hope this helps! :D

If 3t-7=5t, then 6t= Whyyyy? I need help with being explained why it's -21....

Alex17521 [72]

Just relax, breathe deeply from the diaphragm, allow the
cleansing air to fill your brain, and take it one step at a time.

You said that 3t - 7 = 5t

OK. Fine.
Let's just find out what 6t is.

Subtract 3t from each side: -7 = 2t

Multiply each side by 3 : -21 = 6t
