The question says boys/girls = 3/4 so if there are 12 boys in the class you can say:
3/4 = 12/?
and ? is the number of girls which is equal to:
? = 12*3/4 = 9
so if there are 12 boys in the class we will have 9 girls in the class :)))
i hope this is helpful
have a nice day
7x - 1 = 4x + 8
3x = 9
x = 9
ABD
7(3) - 1
21 - 1

DBC
4x + 8
4(3) + 8
12 + 8
20
3x - 17 + x + 40 + 2x - 5 = 180
6x + 18 = 180
6x = 198
x = 33
3(33) - 17
99 - 17
82
33 + 40
73
2(33) - 5
66 - 5
61
So for this, this can be written into the equation

(x = number of months, y = total cost).
To solve this problem, we need to plug in 1325 into the y-variable and solve from there.

Subtract 35 on each side to get

Then just divide by 50 on each side, and your answer should be

And because we cannot go past budget, we will have to round down to 25.
In context, the maximum amount of months Abbey can do is 25 months.
Answer
Lauren is wrong. Maybe she added incorrectly??
Step-by-step explanation:
3 * 15 = 45
45 * 8% = 3.60
45.00 + 3.60 = 48.60
