Answer:
The slope is -1/2. The y-intercept is 1. Y= -1/2x+1
Step-by-step explanation:
Since Jin donated his money to charity and he donated $864, that is our total.
We don't know the first amount, so we can call it x.
We don't know the second amount either, but we do know it was 5 times the first, so 5*x = 5x.
We first need to find how much Jin earned for the first song. We need to find x.
x + 5x = 864, then combine like terms6x = 864, then divide both sides by 66x/6 = 864/4x = 144
The fist song made $144. But the second made 5 times that. So we just multiply 144 by 5. 144*5=720.
The final answer is $720.
Answer:$259
Step-by-step explanation:
since we need to increase $250 by 6%, it is useful to find one percent because 1% is easy to find
to find one percent of 250, we move the decimal point(we cant see it right now) from after the number to after 2 giving us 2.50. we need to do this to find one percent because 1% is the same as one HUNDREDth, and since 100 has two zeros, we move the decimal place two spaces.now that we know that 1% is $2.50 ( which is the same as $2.5) we can times that by six which gives us 6%(because one times 6 is 6) to multiply 2.5 by 6, we first multiply 6 by 2 which will give us 12 and then multiply it by 0.5 (because 2 + 0.5 =2.5) 0.5 multiplied by 6 is equal to 3 and 3 + 6 = 9. we know know that 6% of $250 is $9. we now just add 9 to 250 leaving us with $259
