[Question]Austin bought his seven friends each a robot. Each robot costs $8.75. He was charged $7.22 total for tax. He left with $11.53 in change. How much did Austin start with?
[Answer]First we need to find the total amount for the robots. 7 robots * $8.75 per robot = $61.25 in total. Now we need to add in the tax $61.25 for the robots + $7.22 for tax = $68.47 total spent in store. Now to find what was the beginning amount we take the $68.47 total spent in - store + $11.53 in change = $80 to start. The answer is 80.
Q: Today, at the school science lesson, Jake learned that there are 8 more solar systems for every planet in the galaxy. If there are 20 planets in the galaxy, how many solar systems and planets are there altogether?
A: If there are 8 more solar systems for every planet in the galaxy, there are 8 + 1 = 9 solar systems for every planet. Since the number of planets is 20, there are 20 * 9 = 180 solar systems in the galaxy. Altogether, there are 180 + 20 = 200 solar systems and planets in the galaxy. The answer is 200.
