Ms James buys x calculators and y folders to sell, she must buy at least 5 calculators,the folders she buys must be at least twice the number of calculators and if each calculator cost $20 and foldr $5 and she cant spend more than $300, write inequalities to represnt all this info.
1)x more than or equal to 5
2)2y is more than or equal to x
3)20x+5y is less than or equal to 300

your second one is backwards, it said
"..the folders she buys must be at least twice the number of calculators", so ...
y ≥ 2x
