Answer:
640 and 400
Step-by-step explanation:
Cost of books: x and 1040 -x
x sold at a loss of 15%= 0.85 x
1040 -x sold at a profit of 36% = (1040 - x)*1.36
- x*0.85= (1040-x)*1.36
- 0.85x+1.36x= 1040*1.36
- 2.21x= 1414.4
- x= 1414.4/2.21
- x= Rs. 640
- Rs. 1040 - x= R. 400
Lyn's speed is 3 miles per hour.
That is distance travelled in 60 minutes
= 3 miles
So, distance travelled in 25 minutes
= 3 * 25 / 60 miles
= 25/ 20 miles
= 1.25 miles
New speed of Lyn is 5 miles per hour
That is, for travelling 5 miles, time required = 60 minutes
So, for travelling 1.25 miles, time required = 60 * 1.25 / 5 minutes
= 60/ 4 minutes
= 15 minutes.
It will take her 15 minutes, if she runs at a speed of 5 mph.

Answer:
Step-by-step explanation:
n = # cup(s) of flour
<u>1.5</u> muffins x <u>12</u> (dozen muffins) > fractions
3.5 cups of flour n
12 x 3.5 = 1.5 (n)
42 = 1.5 (n) > multiply 12 and 3.5
42/1.5 = n > divide 1.5 on both sides, cancels out on right
28 = n # cups of flour
1/3 is the answer, 10 = 1/3 20= 2/3 30 = 3/3
