Answer:
x+3≤20
x≤17
Step-by-step explanation:
let the amount of money left for misc expenditures = x
Number of pencils bought = 6
cost of each pencil = $0.50
Total expense on pencil = 6 x $0.50 = $3
Total expenditure =x+3
Maximum expenses allowed = $20
Hence
Total expenditure must be less than or equal to $20
Hence
x+3≤20
Subtracting 3 from both sides
x≤17
