Just simple proportions:
12(apples) x(apples)
-------------- = --------------
4(oranges) 7(oranges)
12*7 = 84
84/4 = 21
There are 21 apples + 7 oranges = 28 apples and oranges!
Answer:
$27.59
Step-by-step explanation:
1) First we calculate the sales tax:
30 x .15 = 4.5
30 - 4.5 = 25.5
2) Now we calculate sales tax
25.5 x .082 = 2.09
25.5 + 2.09 = $27.59


hope this helps!
p.s. can i have brainliest?
2 less than (3 times a number) is the same as (the number plus 10)
2 less than (3*x) = (x + 10)
3x - 2 = x + 10
From here, you solve! :)
3x - 2 - x = x + 10 - x
2x - 2 = 10
2x - 2 + 2 = 10 + 2
2x = 12
2x / 2 = 12 / 2
x = 6
Hope this helps! :)
