A museum opened at 8:00 a. m. in the first hour, 350 prople purchased admission tickets. in the second hour, 20% more people purchased admission ticks than in the first hour. Each admisssion tickets cost $17.50.

What was the total amount of money paid for all the tickets purchased in the first two hours?

First find the total amount of money paid in the 1st hour by multiplying 350 by 17.50.

350 × 17.50 = 6,125

$6,125.00 were paid for the 1st hour.

Now let's find the total amount of money paid for the 2nd hour.

First, find 20% of 350. Turn 20% into a decimal by dividing by 100.

20% ⇒ 0.2

Now multiply 0.2 by 350.

350 × 0.2 = 70

Since 20% more people came in the 2nd hour, add 70 to 350.

350 + 70 = 420

Now you can find the amount paid by multiplying 420 by 17.50.

420 × 17.50 = 7,350.

$7,350.00 were paid for the 2nd hour.

Add the two amounts together to find the total amount of money paid for all the tickets purchased in the first two hours.

6,125 + 7,350 = 13,475

$13,475 was paid for all the tickets purchased in the first two hours.

7x - 49

7(x - 7)

18x + 9

9(2x + 1)

15x - 10

5(3x - 2)

step-by-step explanation:

for number one all you have to do is factor 5 out of 5x + 40

for number 2 factor 7 out of 7x - 49

for number three factor 9 out of 18x + 9

for number four factor 5 out of 15x - 10
