Answer:
Step-by-step explanation:
Firstly, we can simplify the ratio of boys to girls to
1
:
2
.
Then, to find out how many students each ratio represents, we add up
1
and
2
to get
3
(
1
+
2
=
3
).
By dividing
3
by the number of students, we can find how many students ONE ratio represents:
24
3
=
8
.
So ONE ratio is equal to
8
boys. Since our simplified ratio of boys to girls is
1
:
2
already, we do not have to do further multiplying - the number of boys is simply
8
.
For the girls, simply multiply
2
by
8
to get
16
.
Check:
8
boys
+
18
girls
=
24
students
.
She earned $184 in interest.
$644 in all.
Here's why:
The formula is interest = principal x rate x time.
i = 460 x 8% x 5 or i = 460 x 0.08 x 5.
PEMDAS
460(0.08) = 36.8
i = 36.8 x 5
36.8 x 5 = 184
i = $184
To find them in all, add the original amount she deposited with the interest.
460 + 184 = 644
In all: $644
