Question

Please help!! fan/medal

Marco is buying hamburgers and hot dogs for a party and only has $40 to spend. Hamburgers cost $6.49 per pound. Hot dogs cost $4.99 per pound and Marco needs at least 5 pounds of hot dogs. Write a system of inequalities to represent this situation.

Answer 1

Would it be:

6.49h + 4.99 (5) \[6.49h + 4.99 (5) \ge 40\]

Answer 2

if h = hamburgers and d = hot dogs

Answer 3

Actually it would be \[h+hd(5)\le40\]

Answer 4

h= hamburgers and hd=hot dogs

Answer 5

Because remember he only has 40 dollars to spend and he must have 5 pounds of hot dogs. There is no specified amount of hamburgers needed so 5 pounds of hot dogs plus however many pounds of hamburgers must be less than or equal to 40 dollars.

Answer 11

The boys and girls golf teams are trying to raise $750 for an out of county tournament. The boys team is selling candy bars for $2 each. The girls team is selling candles for $4 each. The girls need to sell at least 100 candles to clear out already purchased inventory. Write a system of inequalities to represent this situation.

Answer 12

this one is actually a little confusing for me @SolomonZelman

Answer 13

boy team: y=2x
girl team: y=4x -100

this is what I think.

Answer 14

y=2x for the boy team, because they make 2 dollars per candy, the girls are y=4x because the make 4 dollars per piece. However the girls have to sell 100 pieces to cover the spending.

( I would ask though, and the boys don't have to cover the cost of purchasing candy?! )

Answer 15

Ohhh I see so the girls have to sell 100 candy bars before they can profit from their sales whereas the boys can already begin making profit @SolomonZelman
