Adult tickets cost $4 more than student tickets, if you know that Robert bought 5, then you can multiply 5x4. You can then subtract those $20 from the total of $104, which would bring you to a total of $84. Then you can add the the 5 adult tickets to the 7 student tickets, which would give you a total of 12 tickets. You can then do 84/12= 7 since the cost of every ticket is now equal. Add 4 to the 7 for the cost of the adult ticket. You now have $11 as the cost of an adult ticket and $7 as the cost of a student ticket. Plug everything in to 5a + 7s = 104 if you want to verify the answers. ( a=adult, s=student)

Johnny has a bag with 84 coins in it. If the ratio of dimes to nickels to pennies is 3 to 2 to 1, how many
omeli [17]

Answer:

28

Step-by-step explanation:

Number of coins in the bag ⇒ 84

Give that,

Dimes : Nickels : Pennies

  3       :       2     :   1

You can see that, there are 6 parts . ( 3 + 2 + 1 = 6 )

And now let us write the types of coins in fractions.

Dimes ⇒  \frac{3}{6}

Nickels ⇒ \frac{2}{6}

Pennies ⇒ \frac{1}{6}

And now they're asking for the number of nickels.

To find that, you can multiply 84 ( number of coins) by it's fraction ( 2/6).

Let us solve.

84 × \frac{2}{6}

\frac{84*2}{6}

\frac{168}{6}

28

Therfore, there are 28 nickels.
