To find the total multiply the sale price by 1 + tax rate.
Total = 20 x 1.05
Total = $21.00
100,000 is basically the same thing as 100k
Answer:
<em>4x+7y≤250</em>
Step-by-step explanation:
<u>Inequalities</u>
Let's call:
x = number of small rides
y = number of big rides
Since each small ride costs 4 tickets, x rides cost 4x tickets.
Since each big ride costs 7 tickets, y rides cost 7y tickets.
The total number of tickets is the sum of both:
Total tickets = 4x+7y
The friends have 250 tickets, so the total tickets of the rides cannot be greater than the 250 tickets available, thus:
4x+7y≤250
PEMDAS ( Parentheses, Exponents, Multiplication, Division, Addition, Subtraction)
4(2.53(207))
Since there are no equations in the parentheses, or exponents, we skip these, and head straight for multiplication:
4(523.7)
Then, do multiplication again:
2094.8
So that means, 4(2.53(207)) = 2094.8
I assume the brackets mean parentheses, since the absolute value of 523.7 does not mean anything in this equation.
Answer:
Step-by-step explanation:
c.d. d=11-18=4-11=-7
y=18+(n-1)(-7)
or y=18-7n+7
or y=25-7n
n=1,2,3, ...
