14 weeks
Answers
We may check it with each answer:
In 15 weeks he will earn $850 * 15 = $12 750 In 13 weeks he will earn $850 * 13 = $11 050 In 12 weeks he will earn $850 * 12 = $10 200 In 14 weeks he will earn $850 * 14 = $11 900
Now let's check how much he will spend for general expenses:
In 15 weeks he will spend $300 * 15 = $4 500 In 13 weeks he will spend $300 * 13 = $3 900 In 12 weeks he will spend $300 * 12 = $3 600 In 14 weeks he will spend $300 * 14 = $4 200
In 15 weeks he will have expenses of $12 000 and he will earn $12 750 In 13 weeks he will have expenses of $11 400 and he will earn $11 050 In 12 weeks he will have expenses of $11 100 and he will earn $10 200 In 14 weeks he will have expenses of $11 700 and he will earn $11 900
In 12 and 13 weeks Eduardo won't earn enough money to have a profit, but he will obtain it after 14 and more weeks.

0.985 rounded to the nearest tenth
Answers
They always try to trick you with this. Remember anything 5 or above would round up, anything 4 and under would round down. So look for the tenth place. that's the 9. The number to the right is 8 which is greater than 5. That means round up. You can't round it to 0.1 because that takes it back down. So you just move it over. The answer is 1.0.

A baker has 88 chocolate cookies and 66 vanilla cookies. What is the greatest number of identical cookie bags that can be made without any cookies leftover?
Answers
I think we're looking here for the Greatest Common Divisor: this will be the number of the bags.
What would it be? number 88 and 66 look similar... they're both divisible by 11 (becuase all numbers with two equal digits are) and they're even, so they must be divisible by 22!
88 is 4 times 22 and 66 is 3 times 22.
We know that this is the maximum number, as 3 and 4 don't have a common divisor other than 1:)
So: there will be 22 bags, with 4 chocolate cookies and 3 vanila cookies each!
I think that this is the answer I think there would be 22
