The current value of a baseball card is 60 times its original value v (in dollars). The baseball card is worth $15. Write and solve an equation to find the original value of the baseball card. Equation: =15 Original value: $

0.25

Step-by-step explanation:

From the information given, you can say that the current value of a baseball card is equal to 60 multiplied for its original value and the equation is:

c=60v, where: c is current value and v is original value

Now, you can replace the current value with 15 that is the value of the baseball card and solve for v:

15=60v

v=15/60=0.25

According to this, the original value of the baseball card is 0.25.

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.
