Question

mr. Krabs saw some rickety chairs on sale they were 89.5% off the normal price was $15 each mr. crab four chairs how much did he spend

Answer 1

The normal price of each chair is

$=\text{ \ 15}$

The percentage off the normal price is

$=89.5\text{ \%}$

The percentage of the present price of each chair will be

$\begin{gathered} 100\text{ \% - 89.5 \%} \\ =10.5\text{ \%} \end{gathered}$

To calculate the present value of one chair, we will use the formula below

$=\text{percentag of the normal price}\times normal\text{ price}$

By substituting the values, we will have

$\begin{gathered} \text{new price of each chair will be=}\frac{10.5}{100}\times15 \\ \text{new price of each chair will be}=\frac{157.5}{100} \\ \text{new price of each chair will be}=\text{ \ 1.575} \end{gathered}$

Since Mr .Krabs bought 4 chairs, the amount he spent will be

$\text{Amount spent = price of each chair}\times Number\text{ of chairs}$

By substituting the values, we will have

$\begin{gathered} \text{Amount spent = price of each chair}\times Number\text{ of chairs} \\ \text{Amount spent}=1.575\times4 \\ \text{Amount spent}=\text{ \ 6.30} \end{gathered}$

Therefore,

The amount Mr.Krabs spent is = $6.30
