Antonio’s pizza charge $8.00 for a large pizza and $1.50 for each topping zine’s pizzeria charge $10.00 for a large pizza and $1
hichkok12 [17]
In this problem you would set these two equations equal to each other.
$8+ $1.50x = $10+ $1x 
After this you would simplify the equation to isolate x (being the number of toppings you put on the pizzas) 

$8+ 1.50x =$10+ 1x
-8              -8
----------------------------
$1.50x = $2 + $1x
-1x             -1x
--------------------------- 
$.50x/.50 = $2/.50
_______________
x= 4 toppings and the pizzas would equal $14 total

Wanda is working on her predictions for the next few days. She calculates that there is a 20% chance of rain on Monday and a 20%
Mariana [72]

Answer:

36%

Step-by-step explanation:

the <em>complement </em>of it raining on at least one of these days = it not raining on any day

this means that if it does not rain on at least one day, it does not rain on any day

thus,

1 - probability of it not raining at all = probability it rains at least one day

probability it doesn't rain on monday = 1- 20% = 80%

probability it doesn't rain on tuesday = 1 - 20% = 80%

probability it doesn't rain on monday AND it doesn't rain on tuesday = probability it doesn't rain at all

P(A and B) = P(A) * P(B) = 0.8 * 0.8 = 0.64

1 - 0.64 = 0.36 as our answer
