help me with s.a.t. math questions????????

1.)If 3 kilograms of rose petals are needed to produce 5 grams of perfume, how many kilograms of rose petals are needed to produce 870 grams of perfume?

2.) The only way to produce Brand X muffins is to buy one or more boxes that each contain 6 muffins. Each box costs$1.50. If Alejandro needs at least 20 muffins, what is the least amount of money he could spend?

3.)If the sum of two negative integers is -15 and the product of the two integers is less than 40, then which of the following could be one of the two integers?

4.)If c is positive, what percent of 3c is 9?

5.)A certain box contains only black,blue, and red pens. If a pen is chosen at random from the box, the probability of choosing a black pen is 1/4 and the probability of choosing a blue pen is 1/6. What is the probability of choosing a red pen?

1.)If 3 kilograms of rose petals are needed to produce 5 grams of perfume, how many kilograms of rose petals are needed to produce 870 grams of perfume?

forming a proportion
3000:5=x:870
5x=870*3000
x=870*600 gms
=87*6 kg
=522 kgs

2.) The only way to produce Brand X muffins is to buy one or more boxes that each contain 6 muffins. Each box costs$1.50. If Alejandro needs at least 20 muffins, what is the least amount of money he could spend?
20 muffins=20/6 boxes=4 boxes
cost=4*$1.50=$6.00

3.)If the sum of two negative integers is -15 and the product of the two integers is less than 40, then which of the following could be one of the two integers?
-12 and -3

4.)If c is positive, what percent of 3c is 9?
x/3c*100=9
x=27c/100

5.)A certain box contains only black,blue, and red pens. If a pen is chosen at random from the box, the probability of choosing a black pen is 1/4 and the probability of choosing a blue pen is 1/6. What is the probability of choosing a red pen?
1-(1/4+1/6)=1-(5/12)=7/12

6.)If in a certain sequence the first term is 8 and every subsequent term is determined by adding 15 to the previous term, what is the value of the 50th term?
t50=a+49d
=8+49*15
=8+735
=743
