For the answer to the question above asking how many solutions does the system of equations have? y - 6x = -3 and 4y - 24x = -16. The answer is y - 6x = -3 -6x + y = -3 6x - y = 3 
 4y - 24x = -16 -24x + 4y = -16 24x - 4y = 16 reduces to 6x - y = 4 
and this has no solutions

andre [41]

Answer:

The customer saves 5.9 - 5.5 = $0.5

when he shops at store B

Step-by-step explanation:

Stores A and B sells bananas at different prices per pound.

Bananas are being sold for $0.59 a pound at Store A and $0.55 a pound at Store B.

If a customer wants to buy 10 pounds of bananas from store A and store B,

The customer would spend 0.59 × 10 pounds of bananas = $5.9

buying from store A and

The customer would spend 0.55 × 10 pounds of bananas = $5.5

buying from store B.

The customer spends more for 10 pounds of bananas if he buys from shop A.
