Answer: Tyler mowed the lawn 4 times
Step-by-step explanation:
Let x = number of times that he does laundry
Let y = number of times that he mows the lawn
In one month, he does the laundry 6 more times than he mows the lawn. This means
x = 6 +y
Tyler's parents pay him $ 0.75 to do the laundry and $ 1.75 to mow the lawn. If his parents pay him $ 14.50 that month, it means that
0.75x + 1.75y = 14.5 - - - - - - -1
Substituting x = 6+y into equation 1, it becomes
0.75(6 + y) + 1.75y = 14.5
4.5 + 0.75y + 1.75y = 14.5
0.75y + 1.75y = 14.5 - 4.5
2.5y = 10
y = 10/2.5 = 4
x = 6 + y = 6 + 4
x = 10
Answer:
Easiest and fastest way is to graph both equations into a graphing calc and trace the graph to where they intersect.
Alternatively, you can use substitution to solve for your answer.
