A) \$52
B) \$117
C) \$130
D) \$180
E) \$234

Ratio of hours worked
Makoto : Nishi : Ozuro = 15 : 20 : 30

15 + 20 + 30 = 65
So, Makoto receives 15/65 of the total payment
Simplify to see that Makoto receives 3/13 of the total payment

3/13 of \$780 = (3/13)(\$780) = \$180

Also,

M + N + O= 780
15x + 20x + 30x = 780
65x = 780
x = 12

M= 15x
M = 15 *12 = 180

We are given that Makoto, Nishi, and Ozuro were paid a total of \$780 for waxing the floors at their school. Each was paid in proportion to the number of hours he or she worked. Since Makoto worked 15 hours, Nishi worked 20 hours, and Ozuro worked 30 hours, we can create the following proportion:

Makoto payment : Nishi payment : Ozuro payment = 15x : 20x : 30x

We can create the following equation to determine x:

15x + 20x + 30x = 780

65x = 780

x = 12

Since x = 12, Makoto was paid 15 x 12 = 180 dollars.

Alternate Solution:

Since we know that Makoto’s payment was equivalent to 15x, we know that his payment must be a multiple of 15. Since 180 is the only multiple of 15, the correct answer must be 180.

Here the ratio of three people => 3:4:6
hence 13x=780=> x=60
Now makota was piad 3x => 3*60=> 180

We are given that Makoto, Nishi, and Ozuro were paid a total of \$780 for waxing the floors at their school. Each was paid in proportion to the number of hours he or she worked. Since Makoto worked 15 hours, Nishi worked 20 hours, and Ozuro worked 30 hours, we can create the following proportion:

Makoto payment : Nishi payment : Ozuro payment = 15x : 20x : 30x

We can create the following equation to determine x:

15x + 20x + 30x = 780

65x = 780

x = 12

Since x = 12, Makoto was paid 15 x 12 = 180 dollars.

Alternate Solution:

Since we know that Makoto’s payment was equivalent to 15x, we know that his payment must be a multiple of 15. Since 180 is the only multiple of 15, the correct answer must be 180.

Hi Scott

Does the variable X represent the per hour pay? As when we create the equation 65X=780 we are trying to create (total hours worked*per hour pay = total pay)?

Warm Regards,
Pritish

Since 15x represents the total amount of money that Makoto was paid, then x does mean the hourly pay.

Let the per hour rate be x
15x + 20x + 30x = 65x = 780
x = 12

Makoto was paid = 15x = 15*12= \$180

IMO D
