Answer:
soccer balls = 80
basketballs = 120
Step-by-step explanation:
let S = number of soccer balls sold
let B = number of basketballs sold
If the store sold 40 more basketballs than soccer balls, then
B = S + 40
If the store sold $4800 worth of soccer and basketballs last month at a cost of $33 for a soccer ball and $18 for a basketball, then:
33S + 18B = 4800
Substitute the first equation B = S + 40 into the second equation and solve for S:
33S + 18(S + 40) = 4800
33S + 18S + 720 = 4800
51S + 720 = 4800
51S = 4080
S = 80
Substitute S = 80 into B = S + 40 to find B:
B = 80 + 40 = 120
<span>throw a dice. In this case there is no outcome common as no one and odd number is same. Thus these two events are mutually exclusive or disjoint. </span>
104 total - 32 cookies = 72 brownies.
Ratio of A to B is A/B.
So ratio of brownies to cookies is 72 brownies / 32 cookies = 2.25
You break even if you spend exactly as much as you gain. In other words, if the cost and the revenue are the same:
Subtract 0.25 from both sides:
Divide both sides by 1.25:
So, they must sell 116 computers to break even. If they sell less, they'll lose money. If they sell more, they'll start making profit.
