9. Barbara invests £14,000. In the first year, she earns 5.9% interest. In the second year, she earns 3.2% interest, a. What was
Levart [38]

Answer:

Step-by-step explanation:

Use future value formula to get the total amount at the end of year 1 and year 2;

<u>First, find FV at the end of 1 year.</u>

FV = P(1+r)^n

P = principal amount or amount invested in present value terms = 14,000

r= discount rate = 5.9% OR 0.059 as a decimal

n= total duration of investment = 1

FV = 14,000(1.059)^1

FV= 14,826

<u>Next, find FV of 14,826 at the end of year 2;</u>

P = principal amount or amount invested in present value terms = 14,826

r= discount rate = 3.2% OR 0.032 as a decimal

n= total duration of investment = 1

FV = P(1+r)^n

FV = 14,826 (1.032)^1

FV = <em>15,300. 432</em>

Percentage increase =[ (New value - Old value)/Old value] *100

 = [ (15,300.432 - 14,000)/14,000] *100

= (1,300.432/14,000)*100

= 9.2888

Therefore total percentage increase over the 2 years = <u>9.29%</u>

Noah works at a concession stand selling bags of popcorn and cans of soda. A bag of popcorn costs $2.50 and a can of soda costs
dimaraw [331]

Set up 2 equations:

Total items sold: x + y = 300

This gets rewritten as x = 300-y

The second equation is for total amount made:

2.50x + 1.50y = 522

Replace x in the 2nd equation with the value of x from the first one:

2.50(300-y) + 1.50y = 522

Simplify:

750 - 2.50y + 1.50y = 522

Combine like terms:

750 - y = 522

Subtract 750 from both sides:

-y = -228

Divide both sides by -1 ( to make y positive)

y = 228

Now replace y in the first equation to solve for x:

x+ 228 = 300

Subtract 228 from both sides:

x = 72

He sold 72 bags of popcorn and 228 sodas.

A rope is stretched from the top of a
Mazyrski [523]

Answer:

Step-by-step explanation:

we know two sides of a triangle, one side is 7 feet, the other is 12 feet , so use Pythagoras theorem

C^{2} = A^{2} + B^{2}

C^{2} = 7^{2} + 12^{2}

C^{2} = 49 + 144

C^{2} = 193

C = \sqrt{193}

C = 13.89 feet
