Kim earns $12.80 for every t-shirt she sells for the school fundraiser. The equation 12.8t = m represents the total amount, m, Kim raises for each t shirt she sells. Determine the independent and dependent variable in the scenario and create a table of values with at least 5 ordered pairs that represent the scenario.

Dependent Variable: __________

Answer:

The price of each t-shirt is independent from the total but the total amount depends on the number of t-shirts sold, hence:

  • Independent variable = t
  • Dependent variable = m

The ordered pairs:

  • t = 1 ⇒ m = 12.8*1 = 12.8 ⇒ (1, 12.8)
  • t = 2 ⇒ m = 12.8*2 = 25.6 ⇒ (2, 25.6)
  • t = 3 ⇒ m = 12.8*3 = 38.4 ⇒ (3, 38.4)
  • t = 4 ⇒ m = 12.8*4 = 51.2 ⇒ (4, 51.2)
  • t = 5 ⇒ m = 12.8*5 = 64 ⇒ (5, 64)

Answer:

12.8t=m

  • Here t is independent and m is dependant upon t

Ordered pairs:-

[tex]\\ \sf\longmapsto t(1)=12.8(1)=12.8[/tex](1,12.8)

[tex]\\ \sf\longmapsto t(2)=12.8(2)=25.6[/tex](2,25.6)

[tex]\\ \sf\longmapsto t(3)=12.8(3)=38.4[/tex](3,38.4)

[tex]\\ \sf\longmapsto t(4)=12.8(4)=51.2[/tex](4.51.2)

[tex]\\ \sf\longmapsto t(5)=12.8(5)=64.0[/tex](5.64.0)
