Step-by-step explanation:
Answer:
Jeremy find the cost of the sneakers by solving for the values of the 10% in dollars and subtracting the dollar amount from the cost of the sneaker
Step-by-step explanation:
Step one:
given data
cost of sneakers= $60
Required
the cost of the sneaker after the two discounts
Actually, the two percents given are the discount of the sale.
the first discount is
15%= 15/100*60
=0.15*60
=$9
The second is 10% coupon
10/100*60
=0.1*60
=$6
The total discounts = 9+6= $15
The cost of the sneakers= 60-15= $45
Jeremy find the cost of the sneakers by solving for the values of the 10% in dollars and subtracting the dollar amount from the cost of the sneaker
Move all terms to one sides
3x^2 - 14x - 5 = 0
Split the second term in 3x^2 - 14x - 5 into two terms
3x^2 + x - 15x - 5 = 0
Factor out the common terms in the first two terms, then in the last two terms;
x(3x + 1) - 5(3x + 1) = 0
Factor out the common term 3x + 1
(3x + 1)(x - 5) = 0
Solve for x;
<u>x = -1/3, 5</u>
