A pair of shoes is on sale for 80 percent of the original price. The sale price is $60. What was the original price?

1 answer:

3 0

Answer:

$150

Step-by-step explanation:

let the original price be x

80% of the original price will be

80/100 × x=60

80/100= 2/5

2/5 × x= 60

2x/5 =60

cross multiply

2x = 300

divide both sides by 2

2x/2 = 300/2

x= $150

Answer:

Trinomials in the form $x^2+bx+c$ can often be factored as the product of two binomials.

Step-by-step explanation:

As we know that a polynomial with three terms is said to be a trinomial.

Considering the trinomial of a form

$ax^2+bx+c$

a = 1

$x^2+bx+c$

Trinomials in the form $x^2+bx+c$ can often be factored as the product of two binomials.

For example,

$x^2+7x+10$

$=\left(x^2+2x\right)+\left(5x+10\right)$

$=x\left(x+2\right)+5\left(x+2\right)$

$\mathrm{Factor\:out\:common\:term\:}x+2$

$=\left(x+2\right)\left(x+5\right)$

Therefore, Trinomials in the form $x^2+bx+c$ can often be factored as the product of two binomials.

Interpreting the situation, it is found that Marjorie will have 240 left after paying her penalty.

---------------------

When the piece lands on the red square, the penalty is equal to 30 times the sum they roll on two numbers.
Marjorie rolls 4 and 2, thus, the sum is 6.
The penalty is of $6 \times 30 = 180$
She currently has 420, the penalty removes 180, thus, she will have 420 - 180 = 240 left after paying her penalty.
