If a pizza cost $10 but you pay $6 how late was the pizza if you get a .25 discount for each 30 minutes its late. write algebra equation

8 hours.

Step-by-step explanation:

The pizza house will pay 10 - 6 = 4 dollars in late charges.  Each hour costs them 1 dollar. (0.25 per 1/2 hour 0.50 dollars for 1 hour.)

So 1 hour gives a reduction of 0.50 dollars.

   x hours gives a reduction of 4 dollars.

0.50 x = 4.00 dollars.

x = 4/0.50

x = 8 hours.

If they keep that up, they will be out of business before too long.

93.8

step-by-step explanation:

lets say, first number = x

second number = 3x+7

total = 49

(x)+(3x+7)= 49

4x+7 = 49

4x = 42

x = 42/4

x= 10.5

x= 10.5

3x+7 = 3(10.5)+7 = 93.8
