Gang charges $22.50 per hour for Consulting Services how much was she charged for seven and a half hours of Consulting
Bogdan [553]

Answer

$168.75

Step-by-step explanation:

$22.50 per hour meaning every hour she gets 22.50

half an hour would be half the money so

22.50 * 7 = 157.50

22.50/2 = 11.25


157.50 + 11.25 = 168.75


168.75 is the answer
