Answer:
20
Step-by-step explanation:
First we start off with the Pizza ($13)
Then we add our first 2 toppings to our pizza ($2 + $2 = $4)
And then we add our last 3 toppings to our pizza ($1 + $1 + $1 = $3)
Now we can add all of our costs up to get our answer
$13 + $4 + $3 = 20$
Therefore the cost for this Pizza is $20

Step-by-step explanation:
.
Negative +Negative = Negative
Negative + Positive = negative
Let's start by writing an equation for this. So in overall, there will be 3 tests. Therefore, If the first two average to 92, then the third plus those two individual scores divided by 3 will need to equal 94. Lets call the new score x.
(92 x 2 + x) / 3 = 94
184 + x = 282
x = 98
Johnny will need to get a 98 on the 3rd test to raise his average to exactly 94.
I hope this helps :-)
