Acaravan crossed 1,378 miles of desert in 85 days. it traveled 22 miles on the first day and 28 miles on the second day. if the caravan traveled the same number of miles on each of the remaining days, how many miles did it travel on each of those day?

The caravan traveled 16 miles each day

Step-by-step explanation:

The caravan covers a distance of 1378 miles in 85 days. The first day he covered a distance of 22 miles and the second day it covered a distance of 28 miles. The remaining days will be 85 days minus the 2 days we already know the distance the caravan covered which is 83 days.

According to the question the remaining days he covered has equal distance for each day.

let y = miles covered each day in the remaining 83 days  

So total distance covered in those 83 days is 83 × y

Total distance covered for 85 days = 1378 miles

first day  = 22 miles

second day = 28 miles

Remaining 83 days = 83 × y

1378 = 22 + 28 + 83 × y

1378 - 22- 28 = 83y

1328 = 83y

y = 1328/83

y = 16

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 c. ⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀
