Ms. Derr wants to buy 2 T-shirts and 6 pairs of socks for her nephew. Each pair of socks costs $3.60 and each T-shirt costs $15.80. If she only budgeted for $50, how much is her budget short? Write an equation for each step to show and explain your work.

Step-by-step explanation:

It says that each T-shirt costs $15.80 and each pair of socks costs $3.60.

Ms. Derr wants to buy 2 T-shirts so,

2(15.80)=x

x= $31.60

Ms. Derr wants to buy 6 pairs of socks so,

6(3.60)=y

y= $21.60

Add the x and y together and you get,

x+y= z

31.60 + 21.60 = z

z= $53.20

Now, Ms. Derr has a budget of $50, so to figure out how short her budget is,

53.20-50.00= b

b= $3.20

Ms. Derr is short of her budget by $3.20.

her budget will be shorted $3.80

Step-by-step explanation:

add 15.80 two times for the price of 2 t-shirts = 31.60

then add 3.60 six times to get the price of 6 socks = 22.20

add 22.20 and 31.60 = 53.80

subtract 53.80 and 50.00 = $3.80

the monthly balance will be $75,000

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.
