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.

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

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.
