At dinner rodrigo and his friend spent $24. They left a20% tip and then split the cost. How much did each person pay.

Step-by-step explanation:

so first let's set up our equation

24*1.20/2 (i put the one so you can just multiply and don't have to add)

28.80/2 (we follow pemdas and simplified)

$14.40 is the how much they paid

13

step-by-step explanation:

169-1=168

168-3=165

165-5=160

160-7=153

153-9=144

144-11=133

133-13=120

120-15=105

105-17=88

88-19=69

69-21=48

48-23=25

25-25=0

since it took 13times to completely subtract it hence its square root is 13
