dangina [55]

Answer:

The answer is $44.73 and what ever the explain part said on the question is not reasonable.

Step-by-step explanation:

I say this because there are 5 friends and each bill for them is $7.75 so $7.75 times 5 equal $38.75 and then the extra money for dessert is 2.99 but two times so when u add those two to $38.75 it equals $44.73.

hammer [34]

Answer:

Round 1 = 0 points

Round 2 = 17 points

Round 3 = 25 points

Round 4 = 75 points

Step-by-step explanation:

Determine how many points will be scored in each round in correspondence to the variable 'x':

Round 1:

0(x)

Round 2:

Round 3:

x+8

Round 4:

3(x+8)

We know that the sum of all points made in all rounds is 117. Using this information, we can make an equation:

0(x)+x+(x+8)+[3(x+8)]=117

Now, we solve for x:

x+x+8+3x+24=117

5x+32=117

5x=117-32

5x=85

$\frac{5x}{5} =\frac{85}{5}$

x=17

Now we substitute the calculated value for x in each round:

Round 1:

0(17)=0

Round 2:

(17)=17

Round 3:

(17)+8= 25

Round 4:

(25)*3= 75
