A pair of boots that originally sold for $75.32 are on sale for 22% off.

Vesnalui [34]

Answer:

The boots will be $58.75

Step-by-step explanation:

first you cross multiply

$\frac{x}{75.32}$ x $\frac{22}{100}$

you then get 1,657.04= 100x, so divide by 100 on both sides to get

16.5704 = X

Subtract X (the 22% discount amount) from the original price to get the new price of $58.75!

Caleb bought groceries and paid

lutik1710 [3]

Answer:

Price of Caleb's groceries before tax= $6.4

Step-by-step explanation:

Let price of groceries before tax be = $ $x$

Sales tax % = 2.5%

Sales tax applied = $2.5\% \ of\ x = \frac{25}{100}\times x = \frac{25}{100} x$

Actual sales tax paid = $1.60

∴ $\frac{25}{100}x=1.60$

Multiplying both sides by 100.

$100\times \frac{25}{100}x=1.60\times 100$

$25x=160$

Dividing both sides by 25.

$\frac{25x}{25}=\frac{160}{25}$

$x=6.4$

∴ Price of groceries before tax= $6.4
