Answer:
n=-10/3
Step-by-step explanation:
"Twice the difference of a number n and seven is equal to four less than the product of five and the number n" translates into 2(n-7) = 5n - 4. To solve, isolate the variable n.
2(n-7) = 5n - 4
2n - 14 = 5n - 4
2n - 10 = 5n
-10 = 3n
-10/3 = n
Answer:
$38.64
Step-by-step explanation:
Multiply the original price, $48.60 by 0.75 to get the discounted price. This gets you $36.45. Then multiply this by 0.06 to get the sales tax ($2.187) and add this to the sale price (36.45+2.187). This gets you $38.637 which you would round up to $38.64
