Write an equation where x = Justin's orders 
93 = (x) + (2x) + (x + 5)
Simplify the equation:
93 = 4x + 5 
Subtract 5 from both sides:
88 = 4x
Divide 4 on both sides:
22 = x
Solve for the orders:
x = 22 = Justin
22(2) = 44 = Chang
22 + 5 = 27 = Heather. 


Hope this helps!

Let the # of orders sold by these 3 people be represented by H, C and J.
Then H+C+J=93.
C=2J
H=J+5
Find H, C and J.

Let's eliminate C.  Substitute 2J for C in      H+C+J=93:  H+2J+J = 93
Now let's eliminate H:  Subst. J+5 for H in this last equation:

J+5   +   2J   +   J  =  93   =>       4J + 5 = 93   => 4J = 88.

Thus, J = 88/4 = 22.

J handles 22 orders.
H handles 22+5 (or 27) orders.
C handles the rest:  2(22) (or 44) orders.

Check:  do the numbers 22, 27 and 44 add up to 93, as they must?  Yes.

Juan invest $3700 in a simple interest account at a rate of 4% for 15 years
OleMash [197]

<em><u>Question:</u></em>

Juan Invest $3700 In A Simple Interest Account At A Rate Of 4% For 15 Years. How Much Money Will Be In The Account After 15 Years?

<em><u>Answer:</u></em>

There will be $ 5920 in account after 15 years

<em><u>Solution:</u></em>

<em><u>The simple interest is given by formula:</u></em>

S.I = \frac{p \times n \times r }{100}

Where,

p is the principal

n is number of years

r is rate of interest

From given,

p = 3700

r = 4 %

t = 15 years

Therefore,

S.I = \frac{3700 \times 4 \times 15 }{100}\\\\S.I = 37 \times 4 \times 15\\\\S.I = 2220

<em><u>How Much Money Will Be In The Account After 15 Years?</u></em>

Total money = principal + simple interest

Total money = 3700 + 2220

Total money = 5920

Thus there will be $ 5920 in account after 15 years

9.99x10 ^-2 + 1.11 × 10^-2 i dont have the same scientific calculator as the one from school. Would like to verify my math is co
Rufina [12.5K]
The answer should not depend on which machine or which pencil you use to
find it.  If you work a problem two different ways and get two different answers,
then at least one of them is wrong, and there's a pretty good chance that both
of them are.

(9.99 of anything) + (1.11 of the same thing) = 11.1 of them

9.99 (x 10^-2) + 1.11 (x 10^-2) = <em>11.1 (x 10^-2)</em> .

Can we do any more with that ?

10^-2  =  1 / 10^2  =  1 / 100 .

11.1 x 10^-2  =  11.1 / 100  =  <em>0.111</em>
