Please Help Tiffany bought 2 hotdogs, 2 sodas and 2 hats at the baseball game. The hotdogs cost $1.10 each, the sodas cost $2.25 a piece and the hats were each $5.05. If she paid with a twenty dollar bill, how much change should she get back?

2 hotdogs= 2× 1.10= 2.2

2 Sodas= 2× 2.25 = 4.5

2 hats= 2× 5.05 = 10.1

Then add up: 2.2+4.5+10.1

= 16.8

She paid 20

so her change will be

20- 16.8

= 3.2

4.20

Step-by-step explanation:

1.10 + 1,10 = 2.20

2.20 + 2.25 + 2.25 = 6.70

6.70 + 5.05 + 5.05 = 16.80

so she spent 16.80 and she must have gotten 4.20 change back.

according to the triangle sum theorem, all the angles in a triangle must add up to 180 degrees. if we know one angle is already 90, we do 180-90=90. the other 2 angles must add up to 90, exactly.
