The owner of a luxury motor yacht that sails among the 4000 Greek islands charges $540 per person per day if exactly 20 people s
lora16 [44]

Answer:

Step-by-step explanation:

Charges up to 20 passengers = $540 per person per day

Total charges = 540 × 20 = $10800

If x passengers above 20 sign up for the cruise then total number of passengers = (20 + x)

Total revenue = $(20+x)

But each fare is reduced by $7 for additional passenger above 20 then revenue generated R(x) = 540(20+x) - 7x

R(x) = 10800 + 540x - 7x

R(x) = 10800 + 533x

a). Revenue per day realized R = 10800 + 533x

b). R(48) = 10800 + 48×533

              = $36,384

C). R(78) = 10800 + 78×543

              = $53,154

Write the slope-intercept form of the question of the line through the given point with the given slope.
Alexxx [7]

Answer:

y=x

Step-by-step explanation:

Slope intercept form of a line

y = mx+b

m is the slope

y = 1x+b

Substitute in the point

1 = 1*1+b

1 = 1+b

Subtract 1 from each side

1-1 =1-1+b

0=b

y = 1x

y=x

Mandi learned that each 10% of charge on her cell phone gave her an hour and twenty minutes of use. While playing a game today o
Sonja [21]

Answer:

3hrs 12 mins

Step-by-step explanation:

For every 10% charge she gets 1hr 20mins (or 80 mins)

Charge drop = (81% - 57%) = 24%

Since 10% gives 80 mins;

          24% gives (24/10) x 80 mins = 192 mins

since 1hr = 60 mins

192 mins = 192/60 = 3hrs 12 mins
