Answer 1

Answer: The amount of money spent on t-shirt is $140.

Step-by-step explanation:

Let the cost of t-shirt be 'x'.

Number of dollars Mr. Green has = 200 dollars

Number of dollars Mrs. Green has = 180 dollars

After the purchasing the same shirt, the ratio of remaining number of dollars is 3:2.

According to question,

$\dfrac{200-x}{180-x}=\dfrac{3}{2}\\\\2(200-x)=3(180-x)\\\\400-2x=540-3x\\\\3x-2x=540-400\\\\x=140$

Hence, the amount of money spent on t-shirt is $140.
