In store a, a video game that regularly sells for $59.99 is on sale at 10% off. in store b, the same video game regularly sells for $64.99 and is on sale at 15% off. which store sells the video game for the lower sale price?

Store A: $59.99 for 10% off

Store B: $64.99 for 15% off

Store A;

Multiply 59.99 by 0.10.

59.99 * 0.10 = 5.999

Subtract 5.999 from 59.99.

59.99 - 5.999 = 53.99

Store A: $53.99

Store B; multiply 64.99 by 0.15.

64.99 * 0.15 = 9.7485

Subtract 9.7485 from 64.99.

64.99 - 9.7485 = 55.24

Store B: $55.24

Store A sells the video game for the lower sale price.

ratios represent a pattern or relationship that can be scaled.

equivalent ratios are pairs of ratios that represent the same relationship between quantities, and can be generated by multiplying or dividing both quantities in the ratio by the same factor.

in this lesson, students will use double number lines and ratio reasoning to solve ratio problems. by partitioning double number lines into proportionate intervals, students will build an understanding of equivalent ratio relationships as those that are generated by multiplying or dividing two related quantities by the same number. this lesson will build upon students' prior understanding of multiplicative comparisons, number line reasoning and equivalent fractions (while highlighting the difference between equivalent fractions and equivalent ratios); and will build toward future work in this unit on building ratio tables, and work in future grades in proportionality, scaling, and expressing and graphing linear functions.
