In a rectangle, opposite sides are congruent.

So this means that
QT = RS
or
30 = 4x + 10
subtract the 10 from both sides

20 = 4x
divide both sides by 4

5 = x

answer is B. 5

Ramiro buys 50 packs of candy bars for $40 before a tax of 7.5%. He sells each candy var for 175% of what he paid before tax. ho

Zepler [3.9K]

Answer:

Cost price of each candy = $0.80, Selling price of each candy = $1.40

Step-by-step explanation:

Given:

Ramiro buys 50 packs of candy bars for $40 before a tax of 7.5%.

He sells each candy var for 175% of what he paid before tax.

Question asked:

How much does he buy each candy bar for ?

How much does he sell one for ?

Solution:

<u>By unitary method:</u>

Cost of 50 packs of candy bars = $40

Cost price of 1 pack of candy bars = $\frac{40}{50} =\$0.8$

Cost price of each candy = $0.80

Thus, he buy each candy bar for $0.80

Now:-

As he sells each candy var for 175% of what he paid before tax:-

Selling price of each candy = 0.80 $\times$ 175%

= $0.80\times\frac{175}{100} =\frac{140}{100}=\$1.4$

Thus, he sell one candy for $1.40
