Tom has a jar of quarters and dimes. he has q quarters and d dimes. write an expression that represents the total value in cents of the coins in the jar using the variables q = q=the number of quarters in the jar and d = d=the number of dimes in the jar.

25 p+10 q

Step-by-step explanation:

Given : Tom has a jar of quarters and dimes. he has q quarters and d dimes.

Let q = the number of quarters in the jar and d =the number of dimes in the jar.

We know that 1 quarter =25 cents

And 1 dime =10 cents

Then, Value of p quarters=25p

Value of q dimes=10 q

Thus the total value of the coins ( in cents) = 25p +20 q

Therefore, the expression that represents the total value in cents of the coins in the jar :-

25p+10q
