Andrea has $18 to spend. She spent $6.50, including tax, to buy a notebook. She needs to save $5.75, but she wants to buy a snack. If candy bars cost $1.15 per package including tax, what inequality would show the maximum number of packages that Andrea can buy? Solve your inequality by showing your work and steps. plz plzpllzpzllzp help me

The number candy bar packages must be less than or equal to  5 . The maximum number is 5.

Step-by-step explanation:

Let the number of candy bar packages be  n .

6.50  -  5.75

Now we can drop the dollar signs from every number and simplify.

18  -  6.5  -  1.15n   ≥   5.75

11.5  -  1.15n   ≥   5.75

Subtract  11.5  from both sides of the inequality.

-1.15n  ≥  -5.75

Divide both sides by  -1.15  and flip the inequality sign.

n   ≤  5

The number candy bar packages must be less than or equal to  5 . The maximum number is 5.

step-by-step explanation:

he climbs 300 ft/hr at a constant rate. the peak is at 1,500 ft.

when going up, he reaches 600 ft in 2 hours. remember, that he is going in a constant rate. divide 600 with 300:

600/300 = 2

assuming that he takes the same route back (meaning that it's a 1500 ft route back, you can solve.

note also that you are solving when he gets back to 600 ft after he reaches the peak.

first, find the amount of hours it takes to get up the peak. divide the total amount (1500), with the ft/her (300) to get the amount of hours (x):

1500/300 = x

x = 5

it takes jamie 5 hours to get up. now, he is returning down, and reaches 600 (his current destination). remember that he climbs at a constant 300 ft/hr. divide 600 with 300:

600/300 = x

x = 2

now add the two numbers together.

x = 5 + 2 = 7

jamie takes 7 hours to go up the mountain and reach his current position when descending.

(total amount/constant rate) = (time).

remember that it is a constant rate, so in total, when he gets back down the mountain, it will take the same amount of time as when he goes up. the total amount for the round trip is: 5 + 5 = 10.
