Let x be the number of t-shirts that can be bought.
The cost of one t-shirt is $12.
The total amount spent on x t-shirts is then 12x.
You also have a coupon worth $5 off.
After applying the coupon, the total amount spent on x t-shirts is then 12x - 5.
You have $43 to spend at the mall.
So, the equation is 12x - 5 = 43.
To solve the equation, we can add 5 to both sides to isolate the term with x:
12x - 5 + 5 = 43 + 5,
12x = 48.
Then, divide both sides by 12:
12x/12 = 48/12,
x = 4.
Therefore, you can buy 4 t-shirts using your coupon and money. Answer: 4 shirts.
To find out how many t-shirts you can buy with your coupon and money, let's set up an equation.
Let x represent the number of t-shirts you can buy.
The cost of each t-shirt is $12. With the $5 coupon, you will have $12 - $5 = $7 left to spend on t-shirts.
So, the equation is: 12x + 7 = 43.
Now, let's solve the equation to find the value of x.
Subtracting 7 from both sides of the equation:
12x + 7 - 7 = 43 - 7,
Simplifying:
12x = 36.
Dividing both sides of the equation by 12:
12x / 12 = 36 / 12,
Simplifying:
x = 3.
Therefore, you can buy 3 t-shirts using your coupon and money.
The answer is: 3 shirts.
