Katarina is buying types of bird seed by the pound. For 11.00, she can buy 2 pounds of thistle seed and 1.5 pounds of sunflower seed. For 23.50 she can buy 3 pounds of thistly seed and 4 pounds of sunflower seed. How much does a pound of sunflower cost

Step-by-step explanation:

2t + 1.5s = 11

3t + 4s = 23.50

6t  + 4.5s = 33

-6t - 8s =   -47

-3.5s = -14

s = $4 a pound for sunflower seeds

since proposition states that a number is greater than 25, if is true then the number must actually be greater than 25.

this implies that all possible options, except 24, can be accepted
