Answer:
9
Step-by-step explanation:
40 dollars due up front
10 dollars made per sale
5 dollars lost per creation
Realistically speaking she is only making a $5 profit per box she sells;
<em>$5 used up for material cost, $10 made from sales </em><em>-5+10= 5</em>
To pay the $40 dollar for the booth she would need to make 9 sales with her current profit
<em>40/5 = 9</em>
Answer:
x=50
Step-by-step explanation:
(x-10)+x+90=180
2x-10+90=180
2x+80=180
2x=100
<u><em>x=50</em></u>
Part A: c for cost. c=0.31m+0.5
0.31m is the cost per minute. 0.5 is cost per call.
Part B: 0.31m+0.5=5.15 to solve we must rearrange.
subtract 0.5 from each side giving us 0.31m=4.85
divide by 0.31 giving us m=15.65
