Question

Hugo's older sister, S Last year, she worked the entire summer and was paid a salary of $3,000. This summer, she is going to get a 6% raise in pay. To figure out how much she will make, Sandra drew the following diagram. 7-28. Copy the diagram on your paper and fill in the missing information. a. b. Since Sandra's salary is increasing, does it make sense that her scale factor (multiplier) should be less than 1, equal to 1, or more than 1? Wh The diagram shows Sandra's original salary and the amount of the increase. What is the scale factor (multiplier) between her original salary and her new salary? That is, what number could Sandra multiply the original salary by to get the new salary? c. Show two ways that use different scale factors (multipliers) that Sandra can use to compute her new salary. d. 7-29. Miranna teaches gymnastics lessons at summer camp. She is paid $12.50 per hour. If Miranna were offered a raise of 100% per hour, what would her new hourly rate be? What percent of her original pay would she be paid? a. Miranna is offered a raise of 75% of her hourly rate to teach a private lesson. How much per hour would she be paid for the private lesson? What percent of her original pay would she get? b. What is the relationship between the percent raise that Miranna gets and her new pay as a percent of her original pay? How is this related to the scale factor (multiplier) between her original pay and her new pay? c. Chapter 7: Proportions and Percents
