Help!! Sonya went to the movies and bought some refreshments. Popcorn costs $3.50 and drinks cost $1.50 each. If Sonya bought 2 tubs of popcorn and 3 drinks, how much did she spend on refreshments?

Without any equipment, you can see stars that are 2{,}800{,}0002,800,0002, comma, 800, comma, 000 light-years away. by looking through a small telescope, you can see stars that are 3{,}112{,}000{,}0003,112,000,0003, comma, 112, comma, 000, comma, 000 light-years away. approximately how many times as far can you see using a small telescope as without any equipment?
