Question

3 Markers Cost $5.79. Which Equation Would Help Determine The Cost Of 13 Markers?

Answer 1

If we know the cost of 3 markers, we need the unit price to set up an equation for 13 since 13 does not divide by 3 nicely.

$5.79 ÷ 3 = $1.93 for each marker.

If m = marker
1.93m will provide the cost of any number of markers.

Answer 2

First you would find out how much one cost

you do 5.79 / 3= 1.93

then mutliply= 1.93 x 12= $25.09

$25.09 is your answer
