We need a system of equations here, one equation based on the NUMBER of tickets sold and another based on the MONEY earned by the sales. We have 2 different types of tickets: full price (f) and discount (d). The total number of tickets sold is 428; therefore, the first equation is f + d = 428. That accounts for the number of tickets sold. Each full price is 10.25 which can be represented as 10.25f, and each discount ticket costs 8 which can be represented as 8d. The money earned by selling these tickets at those prices was 3946. That means that the second equation is 10.25f + 8d = 3946. We will solve the first bolded equation for f to get f = 428 - d. Sub that value in for f in the second bolded equation: 10.25(428-d) + 8d = 3946. Distribute to get 4387 - 10.25d + 8d = 3946. Combine like terms to get -2.25d = -441. Solving for d we get 196. That means that there were 196 discounted tickets sold. Put that in for d in the first bolded equation to find the number of full price tickets. f + 196 = 428, and f = 232. There were 232 full price tickets sold. There you go!
36 divide 4 equals 9 i know because 9 times 4 equals 36
9 + 9 + 9 + 9 = 36
X=cost of large snack
Y=cost of small snack
X+Y=60
5X+3Y=220
To solve for y, solve x+y=60 for x. Subtract y from both sides so you're left with x=-y+60. You now plug in -y+60 for x in the second equation.
5(-y+60)+3y=220
-5y+300+3y=220
-2y+300=220
-2y=-80
Y=40
40 small snack packs is the final answer
The probability of both children receiving a tablet is 15%.
We have given that
Age of Children P(Tablet) P(Laptop)
Less than 10 0.3 0.02
10-17 0.5 0.4
<h3>What is the probability?</h3>
Probability means possibility. It is a branch of mathematics that deals with the occurrence of a random event. The value is expressed from zero to one.
Probability of both children receiving a tablet is
0.3*0.5 = 0.15 = 15%
Therefore, the probability of both children receiving a tablet is 15%
Therefore option b is correct.
