Astore offers packing and mailing services to customers. this table is given to customers to them estimate the cost of shipping a box based on its weight in pounds, and a flat rate of $5 for packing. which equation represents the shipping cost as a function of x, the weight in pounds? a. f(x) = 2.25x + 5. b. f(x) = 3.5x + 4. c. f(x) = 4x + 9. d. f(x) = 9x + 14

Step-by-step explanation:

A.f(x) = 2.25x + 5

f(x) = 2.25x + 5

Step-by-step explanation:

As given, the cost of shipping a box is based on its weight in pounds, and a flat rate of $5 for packing. This means $5 is common for each parcel that will be sent. Only the weight will vary.

So, option first f(x)=2.25x+5 is the correct answer. Here 2.25 is the per pound rate. Like if someone wants to send a parcel weighing 3 pounds, the price will be :

f(x)=2.25*3 +5

= $11.75

let soccer = x and golf = y

part a

1st equation: x + y = 125

2nd equation: x = y +45

part b

replace x in the 1st equation with the 2nd one:

y + 45 + y = 125

simplify:

2y + 45 = 125

subtract 45 from each side:

2y = 80

divide both sides by 2:

y = 80/2

y = 40

she plays golf for 40 minutes.

part c

no because she plays soccer for 45 minutes longer than golf 40 +45 =   85 minutes, not 80 minutes.
