Vanessa has 6 dimes and 2 pennies. Joachim has i dollar,3 dimes, and 5 pennies. Jimmy has 5 dollars and 7 pennies. They want to put their money together to buy a game that costs 8 dollars. Do they have enough money to buy the game?If not, how much more money do they need?

Step-by-step explanation:

The worth of a dime is 10 cents. Converting to dollars, it becomes

10/100 = $0.1

The worth of a penny is 1 cent. Converting to dollars, it becomes

1/100 = $0.01

Vanessa has 6 dimes and 2 pennies. The total amount of money that she has is

(6 × 0.1) + (2 × 0.01)

= 0.6 + 0.02 = $0.62

Joachim has 1 dollar,3 dimes,and 5 pennies. The total amount of money that she has is

1 + (3 × 0.1) + (5 × 0.01)

= 1 + 0.3 + 0.05 = $1.35

Jimmy has 5 dollars and 7 pennies. The total amount of money that he has is

5 + (7 × 0.01)

= 5 + 0.07 = $5.07

The total amount of money that they have is

0.62 + 1.35 + 5.07 = $7.04

Since the game costs $8, then they don't have enough money. The additional amount of money that they need is

8 - 7.04 = $0.96

54 km / hours

step-by-step explanation:

we need to convert seconds to hours

60 seconds = 1 minutes

60 minutes = 1hour

15 m         60 second   60 minutes

  * *         = 54000 meters/ hour

second     1 minute             1 hour

now we need to convert meters to km

1000 m = 1 km

54000 m       1 km

*   = 54 km / hours

hour               1000m
