Z = k * x
55 = k * 5
divide both sides by 5
11 = x
z = 11x
z = 11 * 12
z = 132
Answer:
First and Second option choices
Step-by-step Explanation:
1st case:
Initial deposit (P) = 500
Annual interest rate (r) = 2.5%
Account balance after x years, y = P(1+r/100)×
y = 500(1+2.5/100)×
y = 500(1+0.025)×
y = 500(1.025)×
2nd case:
Initial deposit (P) = 400
Annual interest rate (r) = 2%
Account balance after x years, y = P(1+r/100)×
y = 400(1+2/100)×
y = 400(1+0.02)×
y = 400(1.02)×
15.26 mm. All you gotta do is convert the millimeters to centimeters, and that subtract. Make sure the decimal point is right, tho. :)
