Mr Tom is going to move and needs to rent a moving truck. Company A charges a rate of $40 per day. Company B charges a $60 fee and also a $20 per day rate. For what number of days would the cost be the same? Also, if Mr. Tom needs the truck for only 2 days, which company should he use? HELP LOTS OF POINTS ASAP

3 days are required for the same cost, and if Mr. Tom wants to rent for two days, then Company A would be cheaper

Step-by-step explanation:

40x = 60 + 20x

20x = 60

x=3

This is for the number of days they will be the same

2 days:

80 = 60 + 40

80 = 100

This compares the rates

hello,

b) 62.47% of the students are between 14 and 18 years old.

step-by-step explanation:

mean = 15 and standard deviation = 2

student between 14 to 18

formula used z-score

for age 14 , z score

using z-table , p(z> -0.5)=0.3085

for age 18 , z score

using z-table , p(z< 1.5)=0.9332

p(-0.5< z< 1.5)=0.9332-0.3085 = 0.6247

thus, 62.47% of the students are between 14 and 18 years old.

step-by-step explanation:

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
