Alejandro uses the steps below to convert

dezoksy [38]

Answer:

The division was computed incorrectly.

Step-by-step explanation:

Given

Workings:

$\frac{5}{8}$ to percentage

$\frac{8}{5} = 1.6 = 160\%$

Required

Explain his error

The question says 5/8

Instead, Alejandro's working shows 8/5.

This working is done in an incorrect order and the correct solution is:

Let

$x = \frac{5}{8}$

Solve the fraction

$x = 0.625$

Multiply by 100%

$x = 0.625 * 100\%$

$x = 62.5\%$

Hence, option (a) is correct.

The sale price of a spring break vacation package was $209.99 the travel agent said by booking early you saved $20.00. Find the

prisoha [69]

Answer:

$\%\ decrease = 9.52\%$

Step-by-step explanation:

Given

$Sales\ Price = \$209.99$

$Saved = \$20.00$

Required

Determine the %decrease

First, we need to determine the amount paid

$Amount = Sales\ Price - Amount\ Saved$

$Amount = \$209.99 - \$20.00$

$Amount = \$189.99$

The percentage decrease is the calculated as follows:

$\%\ decrease = -100\% * \frac{Final - Initial}{Initial}$

In this case;

$Initial = Sales\ Price = \$209.99$

$Final = Amount\ Paid = \$189.99$

So; we have:

$\%\ decrease = -100\% * \frac{189.99 - 209.99}{209.99}$

$\%\ decrease = -100\% * \frac{-20}{209.99}$

$\%\ decrease = 100\% * \frac{20}{209.99}$

$\%\ decrease = \frac{2000\%}{209.99}$

$\%\ decrease = 9.52426306015\%$

$\%\ decrease = 9.52\%$ (Approximated)
