2a + 2s = 32, 6a + 7s = 106
Solve for a in the first equation.
2a = 32 - 2s
a = 16 - s
Substitute a into the second equation.
6(16 - s) + 7s = 106
96 - 6s + 7s = 106
96 + s = 106
s = 10
Substitute s into the first equation.
2a + 2(10) = 32
2a + 20 = 32
2a = 12
a = 6
a = 6, s = 10

Answer:
Therefore the most Marney can pay for a case of 20 soda bottles is = $ 25.344
Step-by-step explanation:
Selling price of a bottle = $ 0.99
Mark price of of a bottle = 28 % above the selling price
Mark price of of a bottle = 1.28 × 0.99 = $ 1.2672
Now the payment for 20 soda bottles = 20 × mark price of one bottle
The payment for 20 soda bottles = 20 × 1.2672
The payment for 20 soda bottles = $ 25.344
Therefore the most Marney can pay for a case of 20 soda bottles is = $ 25.344
Answer:
Step-by-step explanation:
