Answer:
11
Step-by-step explanation:
If i am correct n= the days so with the days adding up day 10 juan would have 55 of the 100 candies, day 11 he would have 66. The statement said at least 64, so it would have to be 64 or the closet amount to 64 but it cannot be lower than 64. So there for 66 is the closest to the given amount, and in order for juan to get 64 he would need to take candies out for 11 days.
Answer:
1. $33.00
2. $48.00
3. $3.00
4. $36.40
Step-by-step explanation:
44.00 - 25% = 33 —> $33.00
80.00 - 40% = 48 —> $48.00
9.99 - 70% = 2.997 —> (round the 7 up because it's above 5) $3.00
52.00 - 30% = 36.4 —> $36.40

PEMDAS
parenthasees
exponents
multipilcarion
bla bla bla
that is important to know the differnece between
2x^2 and (2x)^2
2x^2=2*x*x
(2x)^2=2*2*x*x
so
(-3b)^4=-12b^4
pemdase so look at both sides
left side
negative to an even power means result is positive
right side
-12 times b^4
the -12 is not influcnced because that is multiply and exponents come first so it will remain negative
(+)=(-)
false
you could also evaluate it
(-3b)^4=-3b*-3b*-3b*-3b=81b^4
-12b^4=-12b^4
81b^4=-12b^4
divide b^4
81=-12
false
no
