You just installed your new car speakers into your Honda Civic, and your music sounds awesome! The new speakers are presently running a current of 20 amps from your 12-volt car battery. After reading the speaker’s installation manual you notice that the speakers can handle a maximum of 35 amps before overloading, and you begin your search to add a little more juice to your sound system. In a car magazine, you notice that there is a sale on the newest type of electrical wire that cuts electrical resistance in half. Before you buy them you wonder if buying these new wires will work in your car’s stereo system. Will the newest type of electrical wire overload your speakers? PLEASE ANSWER THIS PLEASE

First, think of what you know. you know that the number t the end of the equation will need to be subtracted because it is the money he lost from buying the lawn mower. and your first two weeks have negative profit, so that tells you that c and d are wrong. now you can plug any of the weeks into a and b to see which one works. i'll start with plugging week 1 into a.this isn't right because it says your answer for week one should be -90.so now we need to try the same thing with b.this one got you the right answer, (sometimes if you only check with one of the weeks multiple will work so you need to check with more of the weeks, but it worked out fine here)this means that b is the correct answer.let me know if you need more clarification. i hope this : )

The answer is 30 minutes to an hour
