Joan has a bag of coins. She has three times as many quarters as dimes. How would you represent her total sum of money if d equals the number of dimes?
A. d+3d
B.10d+ 25(3d)
C. (10d+25)3
D.(10d+25)3d
+128661 The answer is B......if the number of dimes = d , then the number of quarters = 3d
And each dime is worth 10 cents and each quarter is worth 25 cents.....so....the total sum (amount) of money is given by :
The value of each dime (in cents) * their number + the value of each quarter (in cents) * their number =
10*d + 25*(3d) = 10d + 25(3d)
