Answer:
B
Step-by-step explanation:
A= approx 3 dollars = 8 ounces
B= approx 5 dollars = 16 ounces
A= 2.99 x 2 = 5.98 to get 16 ounces
B= =4.99 to get 16 ounces
4.99<5.98
It is given that
a+b=20 -------------------- (1)
b+c=30 -----------------------(2)
We have to calculate
3 a + 4 b +7 c
Now multiplying equation(1 )by 3,we get
3 a+ 3 b=60 ----------------------------------(3)
and Multiplying equation( 2) by 4,we get
4 b + 4 c=120 -----------------------------------(4)
Adding expression (3) and (4),we get i.e left hand side of 3 to left hand side of 4 and right hand side of 3 to right hand side of 4.
3 a+ 3 b+ 4 b+ 4 c=60+120
Adding like terms, we get
3 a+ 7 b+ 4 c =180, Which is the required solution.
the answer is b because x is greater than or equal to 0
