Gianna goes shopping with $100 to spend on food for a party. She buys 8 pizzas that all cost the same price, $20 worth of soda and ice cream. If she spent all of her money, what was the cost of each pizza?

10 dollars for each pizza

Step-by-step explanation:

100-20 is 80

80/8=10

I think your getting confused with The ice cream and soda part. If you think about it, it says AND which basically means together, if it said excluding it means not including so together ice cream and soda would be 20 dollars.

on monday rodney ate 1/4th of the sandwich = 3/12

on tuesday he ate 1/3rd of the sandwich = 4/12

therefore in total he has eaten = 3/12 + 4/12 = 7/12

thus we can say that he has eaten 7/12 of the sandwich on monday and tuesday alltogether.

happy to

pls mark as brainliest.
