Answer: Mrs. Alberts spent $1,050 on the floor.
Step-by-step explanation: First lets find the area to get the total amount of square feet by multiply length by width.
12.5 x 7 = 87.5 square ft.
We know that it costs $12 per square foot, and we have 87.5 square feet.
So, multiply 12 by 87.5 to find the cost that Mrs, Alberts will spend on the floor.
12 x 87.5 = 1050, or $1,050 for the total area of the floor.
Answer:
White roses - 7
Red roses - 17
Step-by-step explanation:
Set up proportional equations
White roses = x
Red roses = 3x - 4
Set equal to 24
x + 3x - 4 = 24
4x - 4 = 24
4x = 28
x = 7
x is white roses, so there are 7
Plug x value into red rose equation
3(7)-4
21-4 = 17 red roses
Check
17+7 = 24
Given:
The bag of apples is $6.33 for 3 pounds.
Required:
We need to find the unit rate of the cost of the apples.
Explanation:
Divide the cost of the bag of apples by the number of pounds.
![T\text{he unit rate of the cost of the apples =}\frac{6.33}{3}](https://tex.z-dn.net/?f=T%5Ctext%7Bhe%20unit%20rate%20of%20the%20cost%20of%20the%20apples%20%3D%7D%5Cfrac%7B6.33%7D%7B3%7D)
![T\text{he unit rate of the cost of the apples =\$ 2.11}](https://tex.z-dn.net/?f=T%5Ctext%7Bhe%20unit%20rate%20of%20the%20cost%20of%20the%20apples%20%3D%5C%24%202.11%7D)
