The student council at Douglass High School is selling shirts for spirit week. So far, they have sold 58 long-sleeve shirts: 24
on Monday and 34 on Tuesday. Short-sleeve shirts have been less popular: they sold 18 of them on Monday and 25 on Tuesday. The student council earned $480 on Monday and $675 on Tuesday. 24x+18y=480
34x+25y=675
Now solve the system of equations you selected. What is the price of a long-sleeve shirt?
90/121. There are 11 chips total. Once you pull a yellow one, there are 10 out of 11 left. Then you pull a black one from there, which leaves you with 9 out of 11 chips. Then you multiply 10 out of 11 by 9 out of 11 to get your probability.
