a total of 60c or more.
A stationer has E300 to spend on pencils and scribblers. She buys x pencils at
30c each and y scribblers at 20c each.
(a) Write an inequality to show that she spends not more than E300.
(
b) She wants to buy more pencils than scribblers. Write
another inequality
that satisfies this condition.
(c) Suppose she buys at least 300 pencils. Write a third inequality to illustrate
this.
(d) Show, on the same axes, the graphs of the inequalities that satisfy the
facts given.
(e) List all of the possible points that represent the possible purchases.
