the salesperson earns a fixed cost of $ 30 plus 2/9th of his sales
we have to find how many sales he gets to earn $ 100 for one day
so lets say that the number of sales for the day - x sales
and he earns 2/9th of his sales
therefore amount he earns for x sales is -
this value plus his fixed earnings of $ 30 per day
so the amount he earns is 2x/9 + 30
this equals $ 100
so we can write the following equation
2x = 70 * 9
2x = 630
x = 315
so the amount of sales he earns for that day is 315 sales
Angle A should be equal to 47
Answer:
Step-by-step explanation:
<span>2(x+4)^2 - (3y+5)^3
at x=-3 and y=-1
2(-3+4)^2 - ((3*-1)+5)^3
2 (1)^2 - (2)^3
