Ed parker joined a health club. there was a $49 registration fee, and a $17.50 monthly fee. if ed visits the club 2 times a week for a year, what does each workout cost him?

The cost of each workout is $ 2.49

Step-by-step explanation:

Given :  Ed Parker joined a health club. There was a $49 registration fee, and a $17.50 monthly fee.

also, Ed visits the club 2 times a week for a year.

We have to calculate the cost of each workout.

We first find the cost that Ed Parker paid to joined a health club

Since, There was a $49 registration fee, and a $17.50 monthly fee.

For a year ,

We have 12 months

So total cost = 49 + 17.50(12) = $ 259

1 year has 52 weeks.

Thus, the weekly fee is  

Since, he visits the club 2 times a week

Thus, each workout cost him

Thus, the cost of each workout is $ 2.49

i dony know

step-by-step explanation:

delaney would like to make a 5lb nut mixture that is 60% peanuts and 40% almonds.

she has several pounds of peanuts and several pounds of a mixture that is 20% peanuts and 80% almonds.

let 'p' represent the number of pounds of peanuts needed to make the new mixture, and  

let 'm' represent the number of pounds of the 80% almond-20% peanut mixture.

:

p + m = 5

therefore

m = (5-p)

write an equation based on the percent of peanuts

1p + .2m = .6(5)

replace m with (5-p)

p + .2(5-p) = .6(5)

p + 1 - .2p = 3

p - .2p = 3 - 1

.8p = 2

p = 2/.8

p = 2.5 lbs of peanuts required

then

5 - 2.5 = 2.5 lbs of the peanut/almond mixture required

:

a) what is the system that models this situation?

p + m = 5

1p + .2m = .6(5)
