Kryger [21]
Let x =  price of the bike before a sales tax.

The price after a sales tax of 8% is
x + 0.08x = 1.08x dollars

Because the price paid was $171.18, therefore
1.08x = 171.18
x = 171.18/1.08 = $158.50

Answer: 158.50

Hi guys, I need help to solve this. I can’t understand how the percentage is calculated in (a) and (b) and how the rent is calcu
lana [24]

Answers :

  1. (A) 18.33%
  2. (B) 21.65%
  3. (C) about 173.33
  4. (D) i really have no way of finding the angles for you, you could try to find them yourself; or maybe just leave it blank?
<h3>OK, so judging from the bar shown : </h3>

It looks like <u>Rent</u> takes up 1/3 of the space so 33.33..%

It also looks like <u>Loan Repayment</u> + <u>Savings</u> is another 33.33..% but Savings is slightly larger than Loan Repayment so you could just estimate Savings to be 55% and LR to be 45% of the 1/3 space.

  • 55% of 33.33.. = 18.33%
  • 45% of 33.33.. = 14.99%

LR looks equal to <u>Entertainment</u> making it another <u>14.99.</u>

It also looks like Entertainment + Electricity + Groceries = the last 33.33..%

And since we know <u>Entertainment</u> = 14.99 / 45% of 33.33..

Making <u>Electricity and Water</u> <em>ABOUT</em>  35% of 33.33... which is <u>11.66</u>

And Groceries is somehow 20% of 33.33 = <u>6.66</u>

  • Rent = 33.33..%
  • Savings = 18.33%
  • Loan Repayment 14.99%
  • Entertainment 14.99%
  • Electricity and Water 11.66%
  • Groceries = 6.66%
<h3>All of these added together equal <u><em>ABOUT</em></u> 100%</h3>
