To find the meal price, divide the tip by the tip percentage:

3.25 / 0.20 = 16.25

The cost of the meal is $16.25

Answer: La probabilidad que necesitamos es 0.16.

Step-by-step explanation:

Se nos proporciona que

La probabilidad de que el estudiante sea un senior = 0.22

La probabilidad de que el estudiante tenga una licencia de conducir = 0.30

La probabilidad de que el estudiante sea un senior o tenga una licencia de conducir = 0.36

Buscamos la probabilidad de que el estudiante sea un senior y tenga licencia de conducir.

Según la pregunta,

$P(S\cap D)=P(S)+P(D)-P(S\cup D)\\\\P(S\cap D)=0.22+0.30-0.36\\\\P(S\cap D)=0.16$

Por lo tanto, la probabilidad que necesitamos es 0.16.

an amusement park sells child and adult tickets at a ratio of 8 to 1 on Saturday they sold 147 more child tickets than adult tic

lawyer [9240]

189 tickets were purchased on Saturday. The ratio of children's tickets to adult tickets is 8:1, indicating that 8 times as many children's tickets were sold compared to adult tickets. Let c represent the number of children's tickets and a the number of adult tickets. Therefore, 8a = a + 147. By subtracting a from both sides, we find 7a = 147. Upon dividing both sides by 7, we find a = 21 adult tickets. By multiplying the number of adult tickets by 8, we discover that 21 * 8 = 168 children's tickets. Adding these together gives a total of 168 + 21 = 189 tickets sold on Saturday.

If rs 500 amounts to Rs 725 at 9% simple interest in sometime ,what will Rs 600amount to at 11% in same time?

AnnZ [9099]

Answer:

$Rs\ 930$

Step-by-step explanation:

The formula for calculating simple interest is

$A=P(1+rt)$

Here,

A refers to the Total Amount of Investment

P denotes the Initial Investment

r indicates the interest rate

t represents the duration in time periods

step 1

Determine the duration t

For this scenario, we have

$t=?\ years\\ P=Rs\ 500\\ A=Rs\ 725\\r=0.09$

Plugging into the formula above and solving for t

$725=500(1+0.09t)$

$t=[(725/500)-1]/0.09$

$t=5\ years$

step 2

What will Rs 600 grow to at 11% over the same duration?

We have

$t=5\ years\\ P=Rs\ 600\\ A=?\\r=0.11$

Insert into the formula

$A=600(1+0.11*5)$

$A=600(1.55)$

$A=Rs\ 930$

Jamal is comparing his transportation options for an upcoming trip. He’s considering a rental car and a taxi service. Based on h

zzz [9080]

The set of rental car rates making it more economical for Jamal than employing taxi services is outlined as A = {x | 0 ≤ x < 26} [where x represents dollars]. The step-by-step breakdown is as follows: Let the rental cost be $x per day. With Jamal's trip extending over 4 days, factoring in $24 for gas, and estimating taxi costs at around $128, an inequality emerges: 128 > 24 + 4x. Thus simplifying leads to 4x < 104 and consequently x < 26.
