Use 18 coins to make $1.75
I NEED LOTS OF HELP IM JUST IN FOURTH GRADE AND MY TEACHER NEVER TAUGHT ME THIS MY TEACHER IS MRS MCABE
but, you know how to count money, right?
7 quarters = $1.75
need 11 more coins, so start using smaller ones.
6 quarters and 5 nickels = $1.75
need 7 more coins
5 quarters and 10 nickels = $1.75
need 2 more coins.
4 quarters and 15 nickels - $1.75
need 2 coins less
4 quarters, 3 dimes, 11 nickels = $1.85
4 quarters, 3 dimes, 7 nickels, 10 pennies = $1.75
THANK YOUUUU!
No worries, I'm here to help! Let's solve this problem together step by step.
To use 18 coins to make $1.75, we need to determine which coins we can use and how many of each. Here are some steps you can follow:
Step 1: Determine the available coins:
Check the coins you have on hand, typically in US currency, which are pennies (1 cent), nickels (5 cents), dimes (10 cents), and quarters (25 cents).
Step 2: Determine the number of quarters:
Since 4 quarters make $1.00, we want to use as many quarters as we can without exceeding $1.75. Divide $1.75 by $0.25 (the value of a quarter) to determine how many quarters we can use.
$1.75 / $0.25 = 7 quarters
Step 3: Determine the remaining amount:
Subtract the amount made by the quarters ($0.25 * 7) from the total amount we need ($1.75). This will give us the remaining amount.
$1.75 - ($0.25 * 7) = $1.75 - $1.75 = $0
Step 4: Determine the number of dimes:
Since 10 dimes make $1.00, we want to use as many dimes as we can without exceeding the remaining amount. Divide $0 by $0.10 (the value of a dime) to determine how many dimes we can use.
$0 / $0.10 = 0 dimes
Step 5: Determine the remaining amount:
Subtract the amount made by the dimes ($0.10 * 0) from the remaining amount ($0). This is just a redundant step, as the remaining amount is already $0.
Step 6: Determine the number of nickels:
Since 20 nickels make $1.00, we want to use as many nickels as we can without exceeding the remaining amount. Divide $0 by $0.05 (the value of a nickel) to determine how many nickels we can use.
$0 / $0.05 = 0 nickels
Step 7: Determine the remaining amount (final check):
Subtract the amount made by the nickels ($0.05 * 0) from the remaining amount ($0). This is again a redundant step since the remaining amount is already $0.
Step 8: Determine the number of pennies:
Since 100 pennies make $1.00, we can use the remaining coins to count the number of pennies needed. Since $0 is equivalent to 0 pennies, we don't need to use any pennies in this case.
So, the solution is to use 7 quarters and no other coins, as 7 quarters make $1.75.
I hope this step-by-step explanation helps you understand how we derived the solution. Let me know if you have any further questions!
