Bryan wants to purchase a skateboard. He has $50 to spend. he finds one that regularly sells for $70.00 and is on sale for 40% o

Maksim231197 [3]

Bryan has enough to buy skateboard as it will cost $44.94

Step-by-step explanation:

Original price = $70.00

Discount = 40%

Amount of discount = 40% of original price

Amount of discount = $\frac{40}{100}*70$

Amount of discount = $\frac{2800}{100}$

Amount of discount = $28

Price after discount = Original price - amount of discount

$Price\ after\ discount=70-28 = $42\\$

Sales tax = 7% = $\frac{7}{100} = 0.07$

Sales tax amount = Price after discount (0.07)

$Sales\ tax\ amount= 42(0.07) = $2.94\\$

Price of skateboard = Price after discount + sales tax

Price of skateboard = 42+2.94 = $44.94

Bryan has enough to buy skateboard as it will cost $44.94

A student solved the given equation and justified every step except one. What is the missing reason? A) Associative property of

Anna007 [38]

Given:

The statements and reasons to solve an equation.

To find:

The missing reason.

Solution:

If a, b and c are three real number, then

Associative property of addition : $(a+b)+c=a+(b+c)$

Commutative property of addition : $a+b=b+a$

Multiplicative property of equality : $a=b\Leftrightarrow ca=cb$

Distributive property of multiplication over addition : $a(b+c)=ab+ac$

In the given step, $(x+-3)+3$ is written as $x+(-3+3)$ .

It means, only parenthesis are changed, which is possible by Associative property of addition.

So, the missing reason is Associative property of addition.

Therefore, the correct option is A.
