Flor tiene una papelería y vende los lápices en $12 y los bolígrafos en $20. ¿Qué expresión algebraica permite saber cuánto debe cobrar Flor por 10 bolsas que contengan x cantidad de lápices y "y" cantidad de bolígrafos?
Answers
Answer:
c=120x+200y
Step-by-step explanation:
La expresión algebraica debería indicar que el valor total que debe cobrar Flor es igual a 10 que representa el número de bolsas por el resultado de la suma del precio de cada item por la cantidad, lo que se puede expresar de la siguiente forma:
c=10(12x+20y)
c=120x+200y
De acuerdo a esto, la expresión algebraica que permite saber cuánto debe cobrar Flor por 10 bolsas que contengan x cantidad de lápices y "y" cantidad de bolígrafos es c=120x+200y.

The population of bacteria in an
experiment is increasing by 90% each
day. If there were 100 bacteria at the
beginning of the experiment, predict the
number of bacteria in 5 days.
First, complete the equation:
Future Amount = 100(1 +0.90) [?]
Answers
Answer:
5
Step-by-step explanation:
5 makes sense since the period of time this takes place is 5 days. therefore [?] should be 5
The number of bacterias increases in 5 days will be 1790.
What will be the bacterial growth?
The bacteria number is increasing day by day the function which shows the bacterial growth is given as Future amount = 100(1+0.9)⁴'⁵.
Now the bacterial growth will be:-
Future amount = 100 ( 1 + 0.9 )⁴'⁵.
Future amount = 100 ( 1.9 ) ⁴'⁵.
Future amount = 1790
Therefore the number of bacterias increases in 5 days will be 1790.

Answer:
$ 11093
Explanation:
Recall that the formula for compound interest is:
A = P ( 1 + r/ n ) n ( t )
−−−−−−−−−−−−−−−−−−−−−−
where:
A = future value
P = principal (starting) amount
r = annual interest rate, expressed as a decimal
n = number of times the interest is compounded in a year
t = number of years compound interest occurs for
1 . Start by substituting your known values into the formula. Note that the annual interest rate is − 0.15 since the car depreciates (becomes lower in value) each year.
A = 25000 ( 1 + − 0.15 1 ) 1 ( 5 )
2 . Solve for A .
A = 25000 ( 0.85 ) )5
A = 11092.63
