For how many books he got : 4
This is but adding up 3 of $3.95 to get the total of $11.85
You then want to subtract that from $47.65 to get $34.80
You subtract that by the $8.95 4 times so you see he bought 4 books
After you talk about how many books did he buy after that sentence I’m not sure what your saying
1. 437,000,003,000,000
2. 53,000,200
3. 797,619,000,000,132
4. 11,006,007
5. 84,000,037,800
This is the concept of algebra, given that the formula for converting Fahrenheit to Celsius is C=59(F-32), the formula for converting to Fahrenheit from Celsius will be found by making F the subject of our formula:
C=59(F-32)
divide both sides by 59
C/59=F-32
adding 32 on both sides we get:
C/59+32=F
hence the formula will be given by:
F=C/59+32
