Chad wants to buy some books over the Internet. Each book costs $10.01 and has a shipping cost of $9.96 per order. If Chad wants to spend no more than $50 for his books, which inequality shows the maximum number of books, p, that he can buy? (5 points)

Select one:
a. 9.96p − 10.01p ≤ 50, so p ≤ 1
b. 9.96p + 10.01p ≤ 50, so p ≤ 2
c. 9.96 − 10.01p ≤ 50, so p ≤ 3
d. 9.96 + 10.01p ≤ 50, so p ≤ 4

a?

Mercury · Answer

hm, not quite, remember that we are adding up the costs not subtracting them

Mercury · Answer

oh whoops I made slight error, the shipping cost 9.96 is the flat cost not the 10.01

so it needs to be 9.96 + 10.01p

Mercury · Answer

that being said, "9.96 + 10.01p" is less than or equal to 50

which inequality best describes this situation?

caira12 · Answer

b

Mercury · Answer

hm, not quite, notice how only the 10.01 is multiplied by p

Mercury · Answer

9.96 not multiplied by p
plus
10.01*p
