Last quarter, Jamal Williams had the following monthly expenditures: January: $1,875; February: $1,643; March: $2,173. His expenses for April were
1.5 times his expenses for February. His expenses for May equal his average monthly
expenditures for January through March. What is Williams' average monthly expenditure for
April through May?
A. $1,897.00 B. $2,464.50 C. $2,180.75 D. $2,010.50

C. $2,180.75

Step-by-step explanation:

Given January: $1,875, February: $1,643, March: $2,173.

And:

$April = ($February × 1.5)

$May = ($January + $February + $March) / 3

We Can Calculate the Monthly Expedenture for all the months.

To start just multiply 1,643 by 1.5 to get the Expedenture for april: 1,643$ × 1.5 = $2,464.5

Then Use the Expedentures you are already given to find the Expedenture for may: ($1,875 + $1,643 + $2,173) / 3 = $5,691 / 3 = $1,897.

Then to find average expidenture of april and may, just sum them(add them up) and divide by 2(total number of months):

($2,464.5 + $1,897) / 2 = $4,361.5 / 2 = $2,180.75.

the circle graph is not a function.

step-by-step explanation:

the graph of the circle is not a function.

because for a graph to be a function, each value of x must give one value of y

in the circle, the values of x for -2< x< 2 each give 2 values of y.

hence this is not a function.
