Here is one of the ways, first you are going to convert the 2% into a fraction.
2% = 0.02
Next we are going to multiply 0.02 * 57 = 1.14
Now we are going to add 1.14 to 57 to find the total cost with including the tax.
1.14 + 57 = 58.14
= $ 58.14
I believe the answer is C
There are 47 dimes and 23 quarters.
Step-by-step explanation:
Total amount = $10.45 = 10.45*100 = 1045 cents
Total coins = 70
1 dime = 10 cents
1 quarter = 25 cents
Let,
Dimes = x
Quarters = y
According to given statement;
x+y=70 Eqn 1
10x+25y=1045 Eqn 2
Multiplying Eqn 1 by 10;
Subtracting Eqn 3 from Eqn 2
Dividing both sides by 15;
Putting y=23 in Eqn 1
There are 47 dimes and 23 quarters.
