Latasha paid $75 to join a summer golf program. the course where she plays charges $30 per round. since she is a student , she receives a $10 discount per round . if latasha spent $375, use the equation 375=20g+75 to find how any rounds of golf latasha played?

Hello!

OK, so first we need to look at our equation which is:

375 = 20g + 75

So it is 20g because she receives $10 discount per round.
Now we need to solve.

375 - 75 = 300

300 ÷ 20 = 15

This tells us that she played 15 rounds. 

Hope this helps! 

36 minutes

Step-by-step explanation:

The equation to determine the time together is

1/a + 1/b = 1/c  where a and b are the times alone and c is the time together

1/90  + 1/ 60 = 1/c

Multiply each side by 180c to clear the fractions

180c( 1/90  + 1/ 60 = 1/c)

2c + 3c = 180

5c = 180

Divide each side by 5

5c/5 = 180/5

c =36
