The population of a colony of beetles grows 30% each week for 10 weeks. If the initial population is 65 beetles , graph the function that represents the situation.

Expresa commuter train leaves downtown sation and travels at a average speed of 55 miles per hour towards the north side sation, which is 50miles away. thirty minutes later, express commuter train #7 leaves north side and travels at a average speed of 35miles per hour towards downtown sation. at the moment the two trains pass each other, how far(in miles) is train #12 from the downtown sation and how long(in minutes) has the #12 train been traveling

I’m still confused on how to work the percentages

Tell whether the two rates form a proportion
