Ms. courtney took all the 7th grade teachers out to dinner. the total bill was $156.22. she left a 20% tip. how much did the meal cost in all? *

$187.46

Step-by-step explanation:

156.22 x .2 = 31.244

So she left $31.24(4) as a tip, so if we add that to $156.22 then you get the total cost.

156.22 + 31.244 = 187.464

$187.46

Hope that makes sense!

from the figure we get,

the x axis shows   the months and,

the y-axis shows the number of satisfied customer.

each line or each cell in upward direction (y-axis) shows 500.

the appropriate scale for the y - axis is: -

a = 2000 customers

b = 4000 customers

c = 6000 customers

d = 8000 customers

e = 10000 customers

f = 12000 customers

g = 14000 customers
