Kylie has $70 to spend on clothes. She wants to buy a pair of jeans for $30 and spend the rest on t-shirts. Each t-shirt costs $8. Which inequality represents the number of t-shirts she can purchase?

Let x be the number of t-shirts Kylie can purchase.

The total cost of t-shirts is 8x.
She wants to spend the rest of her money, which is 70 - 30 = $<<70-30=40>>40.
So the inequality representing the number of t-shirts she can purchase is 8x ≤ 40. Answer: \boxed{8x \leq 40}.
