Answer:
$17.88
Step-by-step explanation:
Let the price of the meal be p. Then:
p(1.07) represents the price including tax but without tip.
p(1.07)(1.15) represents the meal price (p) plus 7% sales tax and 15 % tip on the meal price plus tax.
p(1.07)(1.15) = $22 (that's all she has). Find the meal price. Multiplying 1.07 and 1.15 together, we get 1.2305. Thus, 1.2305p = $22, and:
p = $22/1.2305 = $17.88. The lady can order a meal priced at $17.88 and still have enough left out of her $22 to pay the sales tax and tip amounts.
232,000,000 - 2.32E8
0.00000431 - 4.31E-6
2,320,000,000 - 2.32E9
0.000000000000431 - 4.31E-13
To solve this, do Betty's points (68) and subtract them from Debbies's (e) to get the expression 68-e.
Answer:
The two boards of equal length are 30 inches long, and the third board is 24 inches long
Step-by-step explanation:
First, convert the length of the board to inches. There are 12 inches in a foot, so multiply 7 by 12:
7(12)
= 84
Let x represent the length of the two boards of equal length. The length of the third board can be represented by x - 6, since it is 6 inches shorter than the other two.
Create an equation to represent this and solve for x:
(x) + (x) + (x - 6) = 84
3x - 6 = 84
3x = 90
x = 30
So, the two boards of equal length are 30 inches long.
Subtract 6 from this to find the length of the third board:
30 - 6
= 24
The two boards of equal length are 30 inches long, and the third board is 24 inches long.
