Mario went to a store and bought 3 slices of pizza. The guy at the register said " that would be $3.75". Mario then said "wait, let me add 1 more slice of pizza". How much is his bill now?

$5

Step-by-step explanation:

Cost per slice

3.75 / 3 = 1.25

Cost of 4 slices

1.25 * 4 = 5

$5

Step-by-step explanation:

First, find how much one slice of pizza costs.

Divide Mario's total by the number of slices he got:

3.75/3

= 1.25

So, one slice of pizza costs $1.25

Add this to his total to find how much his bill will be with one more slice:

3.75 + 1.25

= 5

So, his bill will be $5

12

step-by-step explanation:

a triangle's   full angle is 180 degrees so 180 - 156 = 24. 24/2=12
