Yolanda's daily salary is $225
Step-by-step explanation:
The given is:
- Yolanda gave 20% of her daily salary to taxes
- She then put 10% of her remaining salary into her savings
- She is left with exactly $162
We need to find Yolanda's daily salary
Assume that Yolanda's daily salary is $x
∵ Yolanda gave 20% of her daily salary to taxes
∵ Yolanda's daily salary is $x
∴ The taxes = 20% × x
∵ 20% = = 0.2
∴ The taxes = 0.2 × x = 0.2 x
∴ The remaining of her salary = x - 0.2 x = 0.8 x
∵ She put 10% of her remaining salary into her savings
∴ The money in her saving = 10% × 0.8 x
∵ 10% = = 0.1
∴ The money in her saving = 0.1 × 0.8 x = 0.08 x
∴ The remaining of her salary = 0.8 x - 0.08 x = 0.72 x
∵ She is left with exactly $162
∴ The remaining of her salary = $162
∵ The remaining of her salary = 0.72 x
- Equate her remaining salary
∴ 0.72 x = 162
- Divide both sides by 0.72
∴ x = 225
Yolanda's daily salary is $225

Answer:
cost = 1296 × 2 = $2592
Step-by-step explanation:
The concrete is likely a rectangular prism base on it dimension . The width, length and height is known. The volume of the prism should be calculated since the concrete prize is known base on it volume.
volume of a rectangular prism = Lwh
where
L = length
w = width
h = height
volume = Lwh
volume = 18 × 18 × 4
volume = 1296 ft³.
The cost of the concrete is $2 per cubic ft. Therefore, the volume for 1296 ft³ can be calculated below
$2 is the cost for 1 cubic fit
how much for 1296 cubic ft
cross multiply
cost = 1296 × 2 = $2592
