A bag contains pennies, nickels, dimes, and quarters. There are 50 coins in all. Of the coins, 18% are pennies and 36% are dimes. There are 3 more nickels than pennies. How much money does the bag contain?

$5.24

Step-by-step explanation:

First, we need to find how many of each coin type we have. For pennies and dimes, we can take the percentage and divide by two for the number of coins.

18 / 2 = 9 pennies

36 / 2 = 18 dimes

We also know that there are three more nickels than there are dimes.

9 + 3 = 12 nickels

We can subtract the total number of nickels, pennies, and dimes from the total number of coins to get the number of quarters.

50 - 39 = 11 quarters

Then, we do the math to find the value.

9 x 0.01 = 0.09

18 x 0.10 = 1.80

12 x 0.05 = 0.60

11 x 0.25 = 2.75

2.75 + 1.80 + 0.60 + 0.09 = $5.24

y < -3

step-by-step explanation:

-3y - 2 > 7

-3y -2 + 2 > 7+2

-3y > 9

-3y/-3 < 9/-3   (change the inequality sign when multiplying or dividing by a negative number)

y < -3
