Answer:
Gummy bears $3.20/lbs
Jelly beans $7.50/lbs
Step-by-step explanation:
For this we will substitute gummy bear price for "x" and jelly bean price for "y" which creates this system (also assuming there is no sales tax involved):
1.8x + 0.6y = 10.26
1.2x + 1.5y = 15.09
Then once solved, answers come out to be (x,y) = (16/5,15/2) which is (3.2,7.5)

Step-by-step explanation:
Well since you already completed the table, a pattern would be that the left column is twice the amount of the right column ( 30x2=60, 35x2=75,etc.)
By pythagorus theorum In triangle ADC
AD²=AB²-BD²
AD²=(6.2)²-(2.7)²
AD=5.5
Again in triangle ADC
AC²=AD²+BC²
AC²=(5.5)²-(2.5)²
AC²=30.25-6.25
AC=4.8 approx..
