Answer:
0.60a + 0.80p < = 10 <== ur inequality
if u buy 9 apples....a= 9
0.60(9) + 0.80p < = 10
5.40 + 0.80p < = 10
0.80p < = 10 - 5.40
0.80p < = 4.60
p < = 4.60/0.80
p < = 5.75.....the greatest number of pears u can buy (p) is 5
Answer:
She will still have 80 pages left to read after 10 days.

Answer:
6.1
Step-by-step explanation:
If we are rounding at the 0 digit, we look at the next digit, which is 9
9 >= 5 so we need to round the 0 up to 1
6.099 rounds to 6.1
There are 10,000 total four-digit numbers (1000 through 9999).
Multiples of 2 end in 0, 2, 4, 6, and 8. There are 9*10*10*5 = 4500 four-digit multiples of 2.
Multiples of 5 end in 0 or 5. There are 9*10*10*2 = 1800 four-digit multiples of 5.
There is redundancy between the two sets of numbers, namely those that end in 0, which are both multiples of 2 and 5. There are 9*10*10*1 = 900 four-digit multiples of both 2 and 5.
Then there are 4500 + 1800 - 900 = 5400 total four-digit numbers that are either multiples of 2 or 5, which means the remaining 4600 numbers are neither multiples of 2 nor 5.
