1. Read each percent problem and analyze the corresponding student's work.
A ski hat is on sale for 25% off, which is $5 off. What is the original
price of the ski hat?
Adina
(25)5) - 100%
125 - 100X
100X
125
100
125 x
a. Explain what Adina did incorrectly. Then, set up and solve
the problem correctly

i cant see the graph

step-by-step explanation:

i would need to see the dot plot : )

b. 6

step-by-step explanation:

we are given the table representing an exponential function.

we can see from the table that, as x is increasing, the value of y is increasing in the power of 6.

i.e. the following relation is obtained,

x = 1, y = 6

x = 2, y = 36 =

x = 3, y = 216 =

x = 4, y = 1296 =

x = 5, y = 7776 =

so, the geometric series obtained is .

thus, the common ratio is given by = = 6.

hence, the common ratio is 6.
