To find:
Weekly earnings at his part time job.
Solution:
Let x be the weekly earning.
He spend half of his weekly earning, i.e., 
He earns $10 additional dollars for mowing the lawn.
According to the question,
Multiply both sides by 2.
Therefore, his weekly earnings is $36.
16x-15-9x=13
7x-15=13
+15 +15
x=4
Multiply and ull find ur answer
Answer: 68
Explanation:
Let x be the age of Mr Jasmi
y be the age of Miss Haslinda
a + b + c be the age of the 3 children
We can write:
(x + y + a + b + c)/5 = 38
But:
(a + b + c)/3 = 18
a + b + c = 18(3)
a + b + c = 54
Substitute this value to our first equation
(x + y + 54)/5 = 38
x + y + 54 = 38(5)
x + y + 54 = 190
x + y = 190 - 54
x + y = 136
Thus:
Mean age of (mr jasmi and miss Linda) = (x+y)/2
But x + y = 136
=> mean age = 136/2 = 68
