The booster club president wants to know how many T-shirts and how many blanket wraps the club needs to sell to meet their goal of $1000. The T-shirts cost $10 each, and the blanket wraps cost $25 each. Write a linear equation that describes the problem, and then graph the linear equation. 

• 10x + 1000 = y
• 10x + 25x = 1000
• 10x+25y = 1000
• 10x+1000y = 25
