Raul’s grandfather is Miguel, and Raul’s sister is Paula. Raul’s age is the same as his grandfather’s age minus 60 times the age
Effectus [21]

Answer:

P = (65 - R) / 60

Step-by-step explanation:

Raul's grandfather is Miguel

Raul's sister is Paula

We are given that Raul’s age is the same as his grandfather’s age minus 60 times the age of his sister. If we write this mathematically, we have that:

R = M - (60*P)

Where R = Raul's age, M = Miguel's age and P = Paula's age

We are then given that Miguel is 65 years old, this means that M = 65

=> R = 65 - 60P

To find Paula's age, we make P the subject of formula, hence:

60P = 65 - R

=> P = (65 - R) / 60

We can use this expression to find Paula's age.

Nadusha1986 [10]

Answer:

1680 dollars

Step-by-step explanation:

7 + 4 = 11

77  \div 11 = 7

day \: 7 \times 7 = 49h

evening \: 7 \times 4 = 28h

24 \div 4 = 6

6 \times 3 = 18 (hourly \:  pay \: of \: evening \: job)

24 \times 49 = 1176

28 \times 18 = 504

total \: 1176 + 504 = 1680
