Harrison is correct because the 305 in the actual problem is greater than the 300 in the estimate and 57872 is less than 60000. Harrison arrived at his prediction by rounding to the nearest ten thousand and nearest hundred.
Nothing multiplies into the number 23
The equation seems to be invalid. Is that the equation from your homework? Both sides of the equation dont seem to be equal to each other. This equation would have no solution, instead of one or infinite solutions.
Answer:
$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
