4 pints of ice cream are used for 6 sundaes
So,
6 sundaes = 4 pints of ice cream
=> 1 sundaes = 4 pints of ice cream/6
=> 1 sundaes = 4/6 pints of ice cream
=> 1 sundaes = 0.66666... pints of ice cream

<em>
m= minutes</em>
Plan 1: 9+0.13<em>m</em>
Plan 2: 23+0.09<em>m</em>
9+0.13<em>m</em> = 23+0.09<em>m</em>
-9 -9
0.13<em>m</em> = 14+0.09<em>m</em>
-0.09<em>m</em> -0.09<em>m</em>
0.04<em>m</em>= 14
14÷0.04= 350
<em>m</em>= 350
