Respuesta :
Linear equation is the equation in which the highest power of the unknown variable is one. The equation to find m, the number of months it will take for both accounts to have the same amount of money, can be given as,
[tex]112+25m+45=50+60m[/tex]
Thus the option 4 is the correct option.
Given information;
The saving of the first runner is $112.
The amount of gift card the first runner received is $45 and the saving of each month is $25.
The saving of the second runner is $50.
The amount of second runner save each month is $60.
The number of months it will take for both accounts to have the same amount of money is m.
Linear equation
Linear equation is the equation in which the highest power of the unknown variable is one.
As the saving of the first runner is $112. and the amount of gift card the he received is $45. Also his saving of each month is $25. Thus the money saved by him in m months,
[tex]=112+45+25m[/tex]
As the saving of the second runner is $50 and the amount he save each month is $60. Thus the money saved by him in m months,
[tex]=50+60m[/tex]
For the same amount of saving in m months the above two equation must be equal. Therefore,
[tex]112+45+25m=50+60m[/tex]
Rewrite the equation as,
[tex]112+25m+45=50+60m[/tex]
Hence the equation to find m, the number of months it will take for both accounts to have the same amount of money, can be given as,
[tex]112+25m+45=50+60m[/tex]
Thus the option 4 is the correct option.
