A customer purchased 30 flowers for a bouquet. If the number of carnations is 3 less than twice the number of roses, which system of equations can be used to find the number of roses, r, and the number of carnations, c, in the bouquet? Group of answer choices

c + r = 30 & 2c + r = 3

c + r = 30 & 2c − r = −3

c + r = 30 & c + 2r = 3

c + r = 30 & c − 2r = −3
