Abi had 20 cents. She bought x pencils for 3 cents each. If y equals the number of cents left, write an equation that shows the
Vladimir [108]

An equation that shows the dependence of y on x is y=20-3x and the domain of the function is x=[0,6], x \in N.

Total number of cents = 20.

She bought x pencils for 3 cents each.

Let y equals the number of cents left.

So, 3x+y=20.

y=20-3x

Here y must be positive

So, 20-3x>0

20>3x

\frac{20}{3}>x

Domain of a function is the set of values for which the function is defined.

So, x can get values from 0 to 6.

Therefore, the domain is:  

x=[0,6], x \in N.
