Monica has been saving her spare change. So far she has saved 40 coins for a total of $6.25. Some of the coins are quarters (25 cents) and the rest are dimes (10 cents). How many of each coin does she have? Use elimination to solve.

{q+d=40
{25q+10d=625

10 quarters

40 dimes

Step-by-step explanation:

q + d = 40

25q + 10d = 625

25 > 10

q < d

25(10) = 250

10(40) = 400

$2.50 + $4.00 = $6.00

i believe the answer is c.

option: d is the correct answer.

d) none of the above.

step-by-step explanation:

clearly from the figure attached to the question we could see that there is no shape given. hence without any shape given in the figure and after rotation we can't obtained a square pyramid.

since, to obtain a image we need a proper figure of the pre-image so that it can be transformed.

hence, the correct answer is:

d) none of the above.
