Three-eighths of the sum of sixteen times a number and twenty-four. How do you set this up?
patriot [66]
If you break it up:

Three-eighths = 3/8

Sixteen times a number, we'll call the unknown number X, so 16X.

Twenty Four = 24

The sum of 16X and 24 = 16X + 24

We want 3/8 of that sum so we put the sum in parenthesis and we get:

Y = 3/8(16X + 24) where Y is the answer youd get if you knew what X was.

Answer:

The number of quarters Josie has in her collection of 92 coins 28 quarters

Step-by-step explanation:

The given information are

The total number of coins Josie has = 92

Let the number of quarters she has = x

Therefore, 92 = 8 + 3×x

8 + 3×x = 92

3×x = 92 - 8 = 84

3×x = 84

x = 84/3 = 28

x = 28

The number of quarters Josie has in her collection of 92 coins = 28 quarters.
