Answer:
The answer to your question is 32 rose and 8 tulip
Step-by-step explanation:
Data
rose/ 4 = tulip
total number of arrangements = 40
Rose arrangement = R = ?
Tulip arrangement = T = ?
Process
1.- Write equations to solve this problem
R/4 = T
R + T = 40
2.- Solve the system by substitution
R + R/4 = 40
(4R + R) / 4 = 40
4R + R = 4(40)
5R = 160
R = 160 / 5
R = 32
- Find T
32 + T = 40
T = 40 - 32
T = 8
3.- Conclusion
She made 32 rose arrangement and 8 tulip arrangements.
Question 19:
To get the answer we just have to round up the number then multiply...
9.8% = 10%
5.5% = 5%
19.8 = 20%
(Use the rounding rule, but in 2014 the 20 tons actually increase by 10%, this is where me multiply)
Our equation should look like 20(1.10) so far...
In 2015, we would need to increase the quantity by 5%, which means we would multiply that quantity by 1.05.
Answer:
D) 20(1.1)(1.05)
Question 27:
First, let's find out the discount during the sale, we know there was a 40% discount...
When we use percentages we know it's out of 100...so...
450 * (100% - 40%)
450 * (60%)
450 * (0.6
= 270
After the sale it increases by 40%...
100% + 40% = 140%
140% = 1.4
270 x 1.4
= 378
Answer:
C) 378
I hope this helps, hopefully my explanation made sense...
