A soccer ball takes twenty minutes to inflate. Alexia and Ermias are inflating balls, with Alexia inflating 20 balls and Ermias inflating 5 more balls than Alexia. Calculate the total time in minutes they took to inflate all the soccer balls.
Thoughts? Step-by-step reasoning:
To inflate a soccer ball, it takes 20 minutes, and if Alexia inflated 20 soccer balls, she took 20 * 20 = 400 minutes. Ermias has 5 more soccer balls than Alexia, meaning she has a total of 20 + 5 = 25 soccer balls. If each soccer ball takes 20 minutes to inflate, Ermias took 25 * 20 = 500 minutes to inflate all the soccer balls she had. Alexia and Ermias took 400 + 500 = 900 minutes to inflate all the soccer balls.
Thus, the answer is 900.
