Two algorithms were modeled for students to choose from. One built on the student's prior knowledge of setting up and solving proportions. Both algorithms require that students have fluency with their multiplication.
Kayleen has been offered two jobs. The first job offers an annual salary of $32,000. The second job offers an annual salary of $10,000 plus 8% commission on all of her sales. How much money per month would Kayleen need to make in sales to earn enough commission to make more money at the second job?
Today's Learning Target(s): The student will be able to...
- fluently add, subtract, multiply, and divide multi-digit numbers.
- find a percent of a quantity as a rate per 100.
- solve problems involving finding the whole, given a part and the percent.
For Evening Practice, the student is expected to complete...
- page 10 and 11 in Part Six.
I think Kaleen would need to make $2.56 in sales to earn enough commissions for her second job. I got my answer by knowing that 8% of $32.00 would give you how sales she needs to earn in order to get his second job and that is what they want. First I set up a proportion up a proportion, x/$32.00 = 8%/100. Then I solved it by doing cross product. I did 8% times $32.00 which is $256.00 and then I did 100 times "x" which equals 100x. In order to isolate the "x" you have to get rid of the 100. To get rid of the 100 you have to do the inverse of what it tells you to do. In this case I have to divide $256.00 by 100 which get me $2.56 is what the you need to make in sales in order to make more money at the second job.
