If you spent 80% that means you have 20% left, we'll use B as variable
20% x B = 12
0.20/0.20 x B = 12/0.20
B = 60
She will be paid $2,240.
The equation to use for this is: A=P(1+rt)
More specifically:
A = 2000(1 + (0.02 × 6)) = 2240
A = $2,240.00
X + 3x = 12
(Or 4x=12)
the first x is the number of girls then the second x is the girls times 3, which is how many boys there are.
Answer:
the answer is B
Step-by-step explanation:
Substitute the value of y in the equation as -1,
(-1)^2-31(-1)-17 = 1+31-17 = 15
