Lisa and kate are playing a card game, and a total of 900 points has been scored. lisa scored 250 more points than kate. if you let l=l=the number of points that lisa scored, and k=k= the number of points that kate scored, then the problem can be represented by the system:

l+k=900l+k=900 and l=k+250l=k+250

graph the system. how many points did each of them score?

select one:
a. kate = 575 and lisa = 325
b. kate = 250 and lisa = 650
c. kate = 450 and lisa = 450
d. kate = 325 and lisa = 575

If myesha works overtime, she gets paid "time and a half" for every hour she works. in other words, for every hour over 40 hours myesha works each week, she gets her hourly pay plus half her hourly pay. what is myesha's pay per hour when she works overtime?

Marco is studying a type of mold that grows at a fast rate. he created the function f(x) = 345(1.30)x to model the number of mold spores per week. what does the 1.30 represent? how many mold spores are there after 4 weeks? round your answer to the nearest whole number. 1.30 represents the number of mold spores marco had at the beginning of the study; 985 mold spores 1.30 represents the number of mold spores grown in a given week; 448 mold spores 1.30 represents the 30% rate of weekly growth; 345 mold spores 1.30 represents the 30% rate of weekly growth; 985 mold spores
