Finn has, at most, $20 to spend on school supplies. if he has to buy 6 pencils that are fifty cents each, at most, how much does he have left to spend on other supplies? write and solve an inequality to model this situation.

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

9x

$15.40 per mile

step-by-step explanation:

you have to round up to 4 because 6 is over 5 so you have to round the 3 up to 4
