A store bought a tent for $230 andmarked it up 65%. The store sells thetent with an 8% tax, what is the totalcost of the tent?

Len [333]

The cost for buying the tent is $230.

65% was increasesd for selling. Then the rate is

$\begin{gathered} 230\times\frac{65}{100}=14.95 \\ So,\text{ the marked price=230+14.95=}244.95 \end{gathered}$

The tax is 8%. So this is from the marked price.

$\begin{gathered} \frac{8}{100}\times244.95=19.56 \\ 244.95-19.56=225.39 \end{gathered}$

Therefore the total cost of the tent is $225.39.

If you add natalie's age and fred's age, the result is 43. if you add fred's age to 44 times natalie's age, the result is 88

Pavel [41]

Let Natalie be x, and Fred, y.
So based on 1st condition, we get
x + y =43 - Equation 1
â´ x = 43-y - Equation 2
Now based on 2nd condition, we get
44x+y=88
Using x from Equation 2, we get
44(43-y) + y = 88
â´ 44x43 - 44y + y = 88
â´ 1892 -44y + y = 88
â´ -44y + y = 88 - 1892
â´ 43y =1804
â´ y = 1804/43
â´ y = 41.95

Using the value of y in Equation 2
x = 43 - 41.95
â´ x = 1.05

So Natalie is 1.05 yrs and Fred is 41.95 yrs old.

vovikov84 [41]

Answer:

c = 3(b + 1)

Step-by-step explanation:

c = 4b - 1b + 3

4b - 1b = 3b

c = 3b + 3

3 is a common factor of both terms on the right hand side

Factorizing the expression

c = 3(b + 1)
