Avendor sells hot dogs and bags of potato chips. a customer buys 4 hot dogs and 2 bags of chips for $9.00. another customer buys 5 hot dogs and 3 bags of chips for $11.75. find the cost of a hot dog.

hot dog = $1.75

Step-by-step explanation:

Let h represent hot dogs and c represent bags of chips.

Customer 1: 4h + 2c = 9.00  →  3(4h + 2c = 9.00)  →  12h + 6c =  27.00

Customer 2: 5h + 3c = 11.75 → -2(5h + 3c = 11.75)  → -10h - 6c = -23.50

                                                                                       2h        =    3.50

                                                                                      ÷2               ÷2    

                                                                                        h        =    1.75

answer is the third choice:

3x^5+4x^4+x^3+2x^2-10x-7=0
