Best ResponseYou've already chosen the best response.0The total price of a shirt and a cap is $11. If the price of the shirt was doubled and the price of the cap was 3 times its original price, the total price of a shirt and a cap would be $25. What is the price of a shirt and a cap? Price of a shirt is $9, and price of a cap is $2. Price of a shirt is $10, and price of a cap is $1. Price of a shirt is $8, and price of a cap is $3. Price of a shirt is $7, and price of a cap is $4.

Best ResponseYou've already chosen the best response.0Harry had $32. He spent all the money on buying 3 notebooks for $x each and 4 packs of index cards for $y each. If Harry had bought 5 notebooks and 5 packs of index cards, he would have run short of $18. A student concluded that the price of each notebook is $5 and the price of each pack of index cards is $1. Which statement best justifies whether the student's conclusion is correct or incorrect? The student's conclusion is incorrect because the solution to the system of equations 3x + 4y = 32 and 5x + 5y = 50 is (8, 2). The student's conclusion is incorrect because the solution to the system of equations 3x + 4y = 32 and 5x + 5y = 18 is (8, 2). The student's conclusion is correct because the solution to the system of equations 3x + 4y = 32 and 5x + 5y = 18 is (5, 1). The student's conclusion is correct because the solution to the system of equations 3x – 4y = 32 and 5x – 5y = 50 is (5, 1).

Best ResponseYou've already chosen the best response.0Price of a shirt is $9, and price of a cap is $2. Price of a shirt is $10, and price of a cap is $1. Price of a shirt is $8, and price of a cap is $3. Price of a shirt is $7, and price of a cap is $4. Let shirt = s and cap = c \[\large s + c = 11\] \[\large 2s + 3c = 25\] lets sub the first equation \(\large s = 11  c\) into the second \[\large 2(11 c) + 3c = 25\] \[\large 22  2c + 3c = 25\] \[\large 22 + c = 25\] \[\large c = 3\] The price of a cap is 3 Meaning the shirt is 8
