Question

While shopping for clothes, Tracy spent $38 less than 3 times what Daniel spent. How much did Daniel spend ?

Answer 1

Answer:

Equation: $y= 3x-38$

Daniel spent: $x= \frac{1}{3} y+12.6$

Step-by-step explanation:

Here is the complete question: While shopping for clothes, Tracy spent $38 less than 3 times what Daniel spent. Write and solve an equation to find How much did Daniel spend ?

Lets assume amount spent by Daniel is "x".

and assume amount spent by Tracy is "y".

As given, Tracy spent $38 less than 3 times what Daniel spent.

∴ $y= 3\times x-\ 38$

$y= 3x-38$

Hence, $y= 3x-38$ is the equation to show amount that Tracy spent.

To find the amount that Daniel spent, we need to solve the equation.

$y= 3x-38$

Adding both side by 38.

⇒ $y+38= 3x$

Cross multiplying both side.

⇒$x= \frac{1}{3} y+\frac{38}{3}$

∴$x= \frac{1}{3} y+12.6$
