Question

2. A school is collecting books for a book sale.

• The goal is to collect 800 books.
• On Monday, students brought 20 boxes of 18 books each.
On Tuesday, students brought 10 boxes of 13 books each.
Which is the closest to the number of books the school still needs to
collect to meet its goal?
a 200
b. 300
c. 400
d. 700​

Answer 1

300

Step-by-step explanation:

20 boxes of 18 each = 20 times 18 = 300

10 boxes of 13 each = 10 times 13 = 130

add those together = 300 +130 = 490

The school still needs = 490 - 800 = 310

the number closest to 310 is 300!
