Brian is buying fancy fishing lures for an upcoming tournament. spinner baits, s, cost $4 each, and river bugs, r, cost $2 each. brian wants to buy some of each lure and spend no more than $45. which inequality models this situation?

a) 4s + 2r ≤ 45
b) 4s + 2r ≥ 45
c) 4s + 2r < 45
d) 4s + 2r > 45

A)4S + 2R ≤ 45

Step-by-step explanation:

The keyword[s] more than, indicates that the maximum amount Brian will pay will be somewhere between the lowest he can pay and $45. There IS a range of purchase, so we choose the less than or equal to inequality.

I am joyous to assist you anytime.

step-by-step explanation:

i took the test: )

answer: the price of one pound cabbage = $ 0.8

the point (10,8) represents that the cost of 10 pounds cabbage is $ 8

step-by-step explanation:

since, here is a proportional relation between the number of pounds of cabbage (x) and the price in dollars (y).

therefore, we can write,

⇒ y = k x

where k is the constant of proportionality.

now, point (5,4) is in the line.

thus, it will satisfies the above equation of line.

⇒ 4 = 5 k

⇒ k = 0.8

thus, the equation of the line is,

y = 0.8 x

a) for x = 1,

y = 0.8

therefore, the cost of one pound of cabbage is 0.8 dollars.

b) in the below graph (10,8) represents that the cost of 10 pounds of cabbage is 8 dollars.
