PLZ EXPLAIN AND U GET BRAILYEST AND 25 POINTS HALP ASAP PLZ A family of five went to the local carnival. The family consists of dad, mom, a thirteen year old daughter, a 10 year old son, and a three year old son. The prices for all-day passes are shown below. If they bought all day passes for everyone in the family, how much did it cost for a day at the carnival?

A. $84.75

B. $74.80

C. $69.80

D. $68.80

Answer

C

Step-by-step explanation:

14.95+14.95=29.90

19.95+19.95=39.90

39.90+29.90=69.80

step-by-step explanation:

let's assume

number of candles set =x

price of of x candles =p(x)

we are given

a candle maker prices one set of scented candles at $10 and sells an average of 200 sets each week

so, we get point as (200,10)

he finds that when he reduces the price by $1, he then sells 50 more candle sets each week

so, we can find slope

now, we can use point slope form of line

now, we can plug values

we can use point

and find b

now, we can plug it back

and we get

now, we can find revenue

we know that

revenue = price*quantity

so, we get

the answer is d

for problems like this theres an app, its photomath that explains the problem and gives the answer hope i
