950-35x=600. X=10. If Ken has 950 dollars in his account. and he withdraws 35 dollars each week then he can keep this pattern going until the 10th week because 950-600 is 350 and 350 divided by 35 is 10. At the end he will have 600 dollars.
Answer:
The answer is D.
Step-by-step explanation:
....................................................
The answer for this problem is B
Let X = the number of pennies.
The number of nickels would be 2X
A penny is 0.01 and a nickel is 0.05
Now you have:
0.01x + 2(0.05x) = 8.80
Simplify:
0.01x + 0.10x = 8.80
Combine like terms:
0.11x = 8.80
Divide both sides by 0.11:
x = 8.80 / 0.11
x = 80
Pennies = X = 80 total pennies.
Nickels = 2x = 2 *80 = 160 nickels.
