You would do

(1.1)(80,000,000)=88,000,000

That is the total cars for year two. To find the increase you would do

(1.1)(88,000,000)=96,800,000

Then you would subtract year 2 from year three

96,800,000-88,000,00=8,800,000

That gives you ur answer.

Answer:

B) 8, 800, 000

Step-by-step explanation:

The number of cars in year 1= 80,000,000

She found that the number of cars on the roads increases by 10% each year.

Now let's find 10% of 80,000,000

= \frac{10}{100} *80,000,000 = 8,000,000

So the number of cars in year 2= 80,000,000 + 8,000,000

= 88,000,000

Now let's find 10% of 88,000,000.

=  \frac{10}{100} *88,000,000 = 8,800,000

So the number of cars in year 3= 88,000,000 million+8,800,000= 96,800,000

Now we have to find difference in year 3 compared to in year 2.

The difference in the cars in  year 3 compared to year 2= 96,800,000 - 88,000,000

=  8,800,000

Therefore, the answer is B) 8, 800, 000

One pretzel has 20 calories. Write an algebraic expression for the total number of calories in n pretzels.
vredina [299]

Answer:

20n

Step-by-step explanation:

One pretzel has 20 calories. Write an algebraic expression for the total number of calories in n pretzels.

1 pretzel = 20 calories

n pretzel = x

Cross Multiply

x × 1 pretzel = n pretzel × 20 calories

x = n pretzel × 20 calories/1 pretzel

x = 20 n

Therefore, an algebraic expression for the total number of calories in n pretzels = 20n
