Fido weighs 26 pounds more then fifi fifi weighs12 pounds less than rover if the sum of their weights is 71 how much does fifi weight

11 pounds

Step-by-step explanation:

Let the weight of Rover is x pounds.

As Fifi weighs 12 pounds less than Rover, so,

The weight of Fifi = x-12...(i)

As Fido weighs 26 pounds more then Fifi, so,

The weight of Fido = (x-12)+26=x+14.

As the sum of their weights is 71, so,

x+(x-12)+(x+14)=71

x+x-12+x+14=71

3x+2=71

3x=71-2=69

x=69/3

x=23

From equation (i), the weight of Fifi = 23-12=11 pounds.

Hence, the weight of Fifi is 11 pounds.

the revenue of the fitness center, y, is the product of two factors: the number of members and the fee paid by each member. there are 320 members now, but number of members goes down by 10 for each $5 increase in fees, so if x is the number of $5 price increases then members is equal to (320 - 10x). since the fee is currently $45, and the fee increases by $5 for every price bump x, the fee is given by (45 + 5x). so, revenue y is given by y = (320 - 10x)(45 + 5x).
