The most realistic answer is A.
You can start by taking 13.85 and finding 4% of that number. You get 0.554, but you round it to the nearest hundredth making it 0.55. Yes the tax is 0.55 cents, but the problem is asking the price including sales tax. So you add 0.55 to 13.85 and get 14.40.
Answer:
x = 54
Step-by-step explanation:
get the variable and numbers on different sides
x/3 + 6 = 12
x/3 + 6 - 6 = x/3
12 + 6 = 18
x/3 = 18
now im going to multiply each side by 3
x/3 x 3 = x
18 x 3 = 54
x = 54
To determine the answer to this item, we just have to calculate for the length of the sides of the cube.
Cube 1: Side = sqrt(480/6) = 4 sqrt(5)
Cube 2: Side = sqrt(270/6) = 3 sqrt (5)
We divide both sides to get the answer which is equal to 4/3.
It is suitable to start with a "let ..." statement defining the meaning of the variable(s) you use in the problem. Here, problems 1, 2, 4 have you multiply the variable by some constant representing a unit rate. In problem 3, you additionally have to perform some math to find an amount remaining.
1) Let s represent the number of shirts purchased at 24.95 each. Then the total cost in dollars is ...
... 24.95s
2) Let t represent the number of trees watered. Then the total number of gallons of water used is ...
... 30t
3) Let q represent the quantity of marbles given away. Then the number remaining is ...
... 48 - q
4) Let p represent the number of pairs of pants purchased at 32.95 each. Then the total cost in dollars is
