Write an equation and solve to find the solution to the following problem.
You have $43 to spend at the mall and a coupon for $5 off at your favorite store. A t-shirt costs $12. How many t-shirts can you buy using your coupon and money?
Let x be the number of t-shirts you can buy.
The cost of each t-shirt is $12.
Considering the $5 off coupon, the equation becomes 12x - 5.
Since you have $43, the equation is 12x - 5 = 43.
Adding 5 to both sides, the equation becomes 12x = 48.
Dividing both sides of the equation by 12, x = 4.
You can buy 4 t-shirts using your coupon and money. Answer: \boxed{4}.
We can set up an equation to represent the problem. Let's define "x" as the number of t-shirts you can buy.
Since each t-shirt costs $12 and you have a coupon for $5 off, the actual cost per t-shirt will be $12 - $5 = $7.
Therefore, the equation becomes:
7x = 43
To solve for x, divide both sides of the equation by 7:
x = 43 / 7
Dividing, we find:
x ≈ 6.1429
Since you cannot buy a fraction of a t-shirt, we need to round down to the nearest whole number. Thus, you can buy a maximum of 6 t-shirts using your coupon and money.
