Xavier has a lunch food budget of $120 a month. He spends an average of $6 per day on lunch. Create a table and then a graph to represent the relationship. Then write an equation where d represents the number of days and m represents that amount of money he had left.

m= 120 - 6*d

Step-by-step explanation:

budget is $120 per 1 month, spends $6 per 1 day

on the the table you have 2 columns: one labele it "days" and one "$ spent" and fill it in:  

days: 1,2,3,4,..

$ spent: 6, 6*2=12, 6*3= 18, 6*4= 32,...

on the graph lable the horizontal axis "days" and the vertical axis "$ spent"

now plot the points (1,6), (2,12),(3,18), ..., and draw a line trough them

the equation is

m= 120 - 6*d

so after 20 days for example, out of 120 will have m=120-6*20=120-120=0,

$0 wil have in 20 days

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.
