[Part A]

company A                company B
A=3h+75                    B=2h+85

definition of variables
A=company A
B=company B
h=number of hours used

[Part B]
company A would charge less for 5 hours

justification
company A                 company B
A=3(5)+75                   B=2(5)+85
A=15+75                     B=10+85
A=90                           B=90

[Part C]
By using the services of company A instead of company B to rent a truck for three hours you save 7 dollars.
company A:  A=3(3)+75 = 9+75= 84
company B:  B=2(3)+85 = 6+85 = 91
difference: 91-84= 7

Answer:

A)

Company A) would be <em>y = 3x + 75</em>

Company B) would be <em>y = 2x + 85 </em>

company A                 company B

<em>A = 3(5) + 75               B = 2(5) + 85 </em>

<em>A = 15 + 75                 B = 10 + 85 </em>

<em>A = 90                         B = 95 </em>

B)

Company A) so that would give us y = $90

Company B) and this would give us y = $95

C)

Company A- in 3 hours you would spend $84

Company B- in 3 hours you would spend $91

so you save $7 by using A instead of B

Brendan worked 7 11/12 hours on Saturday, on Sunday he worked 84% of the hours he worked on Saturday. How many total hours do he
Vesnalui [34]

Answer:

14\frac{17}{30}hrs

Step-by-step explanation:

Given parameters:

Time worked on Saturday = 7\frac{11}{12}

Unknown:

Total hours he worked last weekend  = ?

Solution:

Since Brendan worked 84% of the time he worked on Saturday on Sunday;

 Time worked on Sunday  = \frac{84}{100}  x \frac{95}{12}   = \frac{133}{20}  

Total time worked last weekend  = Time worked on Saturday + Time worked on Sunday;

Total time worked  =  \frac{95}{12}  +  \frac{133}{20}  

Total time worked = \frac{475 + 399}{60}

Total time worked  = \frac{874}{60}  

Total time worked = \frac{437}{30}   = 14\frac{17}{30}hrs

C= 1.50t * 12.50
The slope of the line is the cost of each topping. Because each individual topping is $1.50, you will multiply it by t (the number of toppings).
