Exercise 6.12 (Solution on p. 113.)
Mr. Boutros wants to invest up to $20,000 in two stocks, Cal Computers and Texas Tools. The Cal
Computers stock is expected to yield a 16% annual return, while the Texas Tools stock promises
a 12% yield. Mr. Boutros would like to earn at least $2,880 this year. According to Value Line
Magazine's safety index (1 highest to 5 lowest), Cal Computers has a safety number of 3 and Texas
Tools has a safety number of 2. How much money should he invest in each to minimize the safety
number? Note: A lower safety number means less risk.

step-by-step explanation:

always plug in x. in this case, x equals 4.

i'm going to first solve 4(2+3x)

1) 4(2+3(4)) use pemdas to solve.

i'm going to multiply whats in the parenthesis first, so 3 times 4=12.

2)4 (2+12) i'm then going to multiply 4 by both numbers in the parenthesis (because multiplying comes before adding)

4 times 2= 8.   4 times 12= 48

4) (8+48)= 56 (answer)

i'm then going to solve 8+12x and plug in 4 for x.

1) 8 +12(4)

multiplying comes before adding, so i'm gonna multiply 12 and 4.

12 times 4= 48.

2) 8+48=56

both equal the same!

i got 86 for this

hope this !

if you need an explanation just ask

answer: 4 meters

step-by-step explanation: to you understand 2/3 better you can do 1 divided by 3 = . then multiply that by the 2 which is .66666666666666667 then you would do 6 x .66666666666666667 which is 4.      

hope this .

the answer is c.
