They worked a total of 285 hours at the shelter last summer. alexis worked 15 hours less then becca. cindy worked 4 more then twice as many hours as becca

Number of Hours Becca worked = 74 hrs

Number of Hours Alexis worked = 59 hours

Number of Hours Cindy worked = 152 hours

Step-by-step explanation:

Given:

Total hours worked by them = 285 hours.

Let the Number of hours worked by Alexis be a

Let the Number of hours worked by Becca be b.

Let the Number of hours worked by Cindy be c.

Hence we can say that;

Now given that:

Alexis worked 15 hours less then Becca

Hence we can say that

Also Given:

Cindy worked 4 more then twice as many hours as Becca

Now Substituting equation 2 and equation 3 in equation we get;

Combining like terms we get;

Hence,

Number of Hours Becca worked = 74 hrs

Number of Hours Alexis worked =

Number of Hours Cindy worked =

total amount to be paid = $19.5

step-by-step explanation:

given ,

original price = $25.99

discount = 25%

discount amount = 25% of original price

discount amount = 25/100   * 25.99

discount amount = $6.49

hence , the total amount to be paid = original price - discount amount

                                                            = $25.99 - $6.49

                                                            =$19.5

total amount to be paid = $19.5
