b. solve the equation
c. does the equation have a solution?
d. does the word problem have a solution?
PLEASE HURRY GUYS ILL GIVE YOU BRAINLIEST

Try this option:

1) if the number of nickel coins is 'n', of quarter coins is 'q', then according to the condition 5 coins is: n+q=5;

2) total sum is 50 cents can be written as 5n+25q=50;

3) Using the two equations it is possible to make up the next system:

Finally,

a. see item 3 above;

b. see item 3 above;

c. one solution, see item 3 above;

d. no, it is not possible to have 1.25 and 3.75 coins, n&q∈Z.

b is the final answer! : )

first, we define the variables:

x: number of years after 1950

f (x): amount of vinyl sold.

then, with the variables defined, we have:

68594 vinyl records were sold in 1958 > f (8) = 68594

91299 vinyl records were sold in 1961 > f (11) = 91299

38720 vinyl records were sold in 1952 > f (2) = 38720

161743 vinyl records were sold in 1967 > f (17) = 161743
