Avendor sells hot dogs and bags of potato chips. a customer buys 5 hotdogs and 2 bags of potato chips for $11.50. another customer buys 3 hotdogs and 5 bags of potato chips for $9.75. find the cost of each items.

Hotdogs cost $2 and potato crisps $0.75.

Step-by-step explanation:

Let the hotdogs cost  $h and the crisps $p

5h + 2p = 11.5

3h + 5p =  9.75

Multiply the first equation by  -5 and the second by 2:

-25h  - 10p = -57.5

6h + 10p = 19.5            Adding these 2 equations:

-19h = -38

h = $2.

Substitute h = 2 into the first equation:

5h + 2p = 11.5

10 + 2p = 11.5

2p = 1.5

p = $0.75.

answer: 1722

step-by-step explanation:

given: the mass of saturn=

the mass of mercury=

the number of times the mass of saturn is greater than the mass of mercury

hence, the mass of saturn is 1722 times greater than the mass of mercury.
