Mary bought an antique clock in its first year its value increased by 30% in the second year its value increased by 30% work out wheather the clock increased decreased or remained the same

Answers

The value of the clock will increase by 69%. Option A is correct.

What are percentages?

The percentage is the ratio of the composition of matter to the overall composition of matter multiplied by 100.

Here,
Mary bought an antique clock in its first year its value increased by 30% in the second year its value increased by 30%.
Let the cost of the clock be $1,
Cost increase by 30%
Cost of the clock = 1 + 1×30% = 1.30

Next year cost increase by again 30%,
Cost of the clock = 1.3 + 1.3×30%
Cost of the clock = 1.3 + 0.39 = 1.69

So the total percentage increase is 69%.

Thus, the value of the clock will increase by 69%. Option A is correct.

Solve the system of equations below. Write your answer as an ordered pair
(x, y).
Solve:
{Y= -3x + 13
{Y= -2x + 1

Answers

Answer:

(12, -23)

Step-by-step explanation:

to find x, substitute the value of y into y

-2x+1=-3x+13

collecting like terms

-2x+3x=13-1

x=12

to find y substitute the value x=12 into any of the equation

y=-3x+13

y=-3(12) +13

y= -36+13

y=-23
