At an office supply store pens are $1.69 per dozen and note pads are $4.59 per dozen . can shirley buy 108 pens and 108 note pads for $50 explain your reasoning

If 1 dozen = 12 pens cost $1.69, then 1 pen costs

If 1 dozen = 12 pads cost $4.59, then 1 pad costs

If Shirley buys 108 pens, she will pay for them.

If she buys 108 pads, she will pay for them.

In total she will pay $15.21+$41.31=$56.52. This sum is greater than $50, so she cannot buy 108 pens and 108 pads.

answer:   expression= p+p*d%

price reduction + sale price = $625

sale price: $p+$p*d%

where d% is the percentage of discount

step-by-step explanation:

original price = p

price went down by $150 price reduction $p*d%

sale price= $ 475

therefore the price before sale is: $625

and the expression that shows the price before sale is: p+p*d%

the correct option is:

b. a value of the variable that makes the polynomial equal to zero.

the root or roots of a polynomial are the values of the variable that makes the polynomial equal to 0. we can find the roots of a polynomial making the expression equal to 0 and then, isolating the variable (it it has just one variable).

for example, given the following polynomial:

the root or zero of the polynomial, can be found by making the expression equal to 0, and then, isolating the variable, so, finding the root we have:

therefore, we have that the root of the polynomial is equal to 2.

we must remember that the number of roots that a polynomial can have, will depend on the degree of the polynomial, a first degree polynomial have will have one single root, a second degree polynomial (quadratic expression) may have two roots and so.

hence the correct option is:

b. a value of the variable that makes the polynomial equal to zero.

have a nice day!
