<human>:  Ava and Emma want to know who is better at the new video game Ava got for her birthday. They are each going to play one level and whoever has the highest score wins. They receive 10 points for every enemy they jump on, 5 points for each berry they collect, and 30 points for every second left on the timer when they finish the level. If Ava jumps on 8 more enemies than Emma and collects 3 more berries, but finishes the level 4 seconds slower, what is the difference between their two scores?
<bot>: How many more enemies does Emma jump on than Ava? ** For jumping on enemies, Emma earns 8 * 10 = <<8*10=80>>80 fewer points than Ava.
How many more berries does Emma collect than Ava? ** For collecting berries, Emma earns 3 * 5 = <<3*5=15>>15 fewer points than Ava.
How many more points does Emma finish the level with than Ava? ** For finishing the level faster, Emma earns 4 * 30 = <<4*30=120>>120 more points than Ava.
How many more points does Emma have than Ava? ** Overall, Emma has 120 – 80 - 15 = <<120-80-15=25>>25 more points than Ava.
