Describe two methods for finding the total price of a bill that includes a 20% tip. which method do you prefer?

Step-by-step explanation:

One way to find the total price including the tip is by multiplying the number by a factor of 1.20, beacuse this factor includes the 20%, actually it represents a 120% of the price.

So, if they say that you have to pay $200, with 20$ tip would be

1.20(200)=240.

It would be $240 with the tipe.

That's how you calculate it.

you have to put the graph on here with the question

step-by-step explanation:

shell's the art director at her local community center. she paid $10 and for each child that attends she earns $4.

for each child she ears $4 that is the slope m = 4

she paid $10, that is the initial amount paid. so 10 is the y intercept b

m =4   and b = 10

y intercept is 10 so the point is (0,10)

we start graph from y intercept (0,10)

slope = 4 . we know slope = rise / run

slope = 4   or 4/1   are same

rise = 4   and run = 1

for rise we move 4 units up and for run we move 1 unit to the right

the graph is attached below

x axis is the number of child she attends

y axis is the amount   she earns
