Using your financial goals from unit 1, complete this planning worksheet to calculate how much you'll need to save.
in the text box below, enter one of your purchase goals.
how much does this cost? you'll need to do some research to answer this question. for example, if your goal is to pay for college, find out what the tuition is for one year. if your goal is to buy a car, look in newspapers and online for prices on the particular car you want.
how much money do you currently have saved?
how much more do you need to reach you goal?
list some steps you can take this year to you save toward this goal.
list some steps you can take next year to save toward this goal.
the rules of exponents say that a polynomial can't have a variable as a denominator. option a violates that rule, since it has x + 3 as a denominator.
q1. flip counts numbers that are in the sequence
777 - 8n . . . for some positive integer n
this expression can be factored as
8(97 -n) +1
which is to say that the numbers in flip's sequence are 1 more than a multiple of 8. the number among the answer choices that matches that description is
129 = 16·8 +1 . . . corresponding to 97-n = 16, or n = 81
flip counted the number 129.
q2. let a and p represent the costs of an apple and a pear, respectively. then we have5a = 6pa = p + 0.15
substituting the expression for "a" in the second equation into the first equation, we get
5(p +0.15) = 6p
5p + 0.75 = 6p
0.75 = p
then 12p = 12·$0.75 = $9.00 is the cost of 6 pears and 5 apples (since 5 apples cost the same as 6 pears).
the cost of interest is $9.00.
