1. The Cajun Heartland State Fair charges $1.25 per ticket for the rides. Johnny bought 25 tickets for the rides and spent a tot
vekshin1

Let number of ride tickets = x tickets and

Total cost of fair admission and ride = $y.

Given cost of each ticket = $1.25 and

Number of tickets = 25 tickets.

Total Cost of 25 ticket  = Number of tickets * cost of each ticket = 25 * 1.25 = $31.25.

Total money spent = $43.75.

Total money spent  =  Fair admission  + Total Cost of 25 ticket

43.75 = Fair addmission + 31.35.

Subtracting 31.25 from both sides, we get

43.75-31.35 = y - 31.35 - 31.35.

12.50 = Fair addmission charge

Therefore, Fair addmission charge = $12.50.

We know slope, intercept form

y = mx+b.

Where, is m the slope (cost of each ticket) and b is the y-intercept( Fair addmission charge)

Plugging values in slope-intercept form, we get

y = 1.25 x+ 12.50.

a) We took x for number of tickets for the rides, and y for total cost of ride tickets and fair admission.

b) We got equation y = 1.25 x+ 12.50.

c) For the equation y = 1.25 x+ 12.50, fix charge for fair admission is $12.50 and cost of each ride ticket is $1.25. Total cost (y) of ride tickets and fair admission will be 1.25 times x number of tickets + $12.50 fair admission charges.

The ratio of females to total students in a mathematics class is 18 to 30. What fraction of the class is male? What percent is m
Vera_Pavlovna [14]

Answer:

2/5 or 40%

Step-by-step explanation:

total students=30

female students=18

That must mean, assuming the rest of the class is binary male=12

12/30=2/5 or 40% if you multiply by 20, then multiply by 100%

(2/5)*20=.40*100%=40%

Bianca works as a content writer for $ 10 an hour and as a library assistant for $ 14 an hour. This month, she worked a combined
trasher [3.6K]

It's given in the question,

  • Bianca works as a content writer for $10 per hour.
  • She works as a library assistant for $14 per hour.

She worked for a combined total of 75 hours for both the jobs this month.

Let c be the number of hours Bianca worked as a content writer.

Her earning for this month as a content writer = $10c

Her working hours as library assistant this month = (75 - c) hours

Therefore, her earning as a library assistant for the month = $14(75 - c)

By adding the earnings as a library assistant and a content writer for the month = $10c + $14(75 - c)

           = (10c - 14c) + 1450

           = $(9c + 1050)

    Therefore, expression for the combined total amount she earned this month will be $(9c + 1050).
