ben wants to buy licorice, jelly beans, or some of each for his party. the licorice costs $4 per pound, and the jelly beans cost $3 per pound. he will spend at least $11 but no more than $15. which system of inequalities models the situation?

a. 4x+3y ≥ 11
4x+3y ≥ 15
x ≥0
y ≥0

b. 4x +3y ≤ 11
4x + 3y ≥ 15
x ≥0
y ≥0

c. 4x+3y ≤ 11
4x+3y ≤ 15
x ≥ 0
y ≥ 0

d. 4x+3y ≥ 11
4x+3y ≤ 15
x ≥0
y ≥0

(picture will also be provided)

 D. 4x+3y ≥ 11

4x+3y ≤ 15

X ≥0

Y ≥0

Step-by-step explanation:

Let x = Number of pounds of licorice.

y= Number of pounds of jelly beans .

Given : The licorice costs $4 per pound, and the jelly beans cost $3 per pound.

Cost of x licorice ( in dollars) = 4x

Cost of y jelly beans (  in dollars) = 3y

He will spend at least $11 but no more than $15.

i.e.

Here ,

It means the required system of inequalities models the situation are:

Here ,

Thus , the option D is the correct answer.

30 miles

step-by-step explanation:

we know that 60 seconds equals 1 minute and 60 minutes 1 hour

44 ft       60 sec     60 min     158400   ft

  *   *   =

1 sec       1 min       1 hour         hour

we know that there are 5280 ft per mile

158400   ft       1 mile         30 miles

  *   =

1   hour               5280 ft     1 hour

so in 1 hour   it can travel 30 miles

50x5=$250
