The bike store marks up the wholesale cost of all of the bikes they sell by 30%. Andre wants to buy a bike that has a price tag of $125. What was the wholesale cost of this bike?

Answer:

$96.15

Step-by-step explanation:

Let x be the wholesale cost of the bike.

Given:

Price tag of a bike = $125.

The bike store marks up the wholesale cost of all of the bikes they sell by 30%.

So we can find the wholesale cost of the bike by the following way.

$\frac{100+30}{100}\times x = 125$

$\frac{130}{100}\times x = 125$

$x=\frac{125\times 100}{130}$

$x=\frac{12500}{130}$

$x=\frac{1250}{13}$

$x=96.15$

Therefore, the wholesale cost of the bike is $96.15.

Joana spent $145 on groceries and after tax the final amount was $156.6. What was the tax rate

777dan777 [17]

Answer:

Step-by-step explanation:

Tax equals the original amount times the tax rate

We can find the tax by taking the amount he paid minus the original amount

tax = 156.6 - 145

tax = 11.6

tax = original amount * tax rate

11.6 = 145 * tax rate

Divide each side by 145

11.6/145 = 145/145 * tax rate

.08 = tax rate

To change this to percent, multiply by 100%

.08*100% = 8%
