Answer: T
=
$
36
Step-by-step explanation: Hmm...
Let's organize this problem.
Since he saved
$
30
, he as
$
30
Now, that is five-sixths of the total cost of the game.
Let's name the total cost
T
.
If we have a fraction of something, say, half of four, we multiply the fraction by the whole.
half of four
1
2
⋅
4
Similarly, two-thirds of the total can be represented as:
5
6
⋅
T
Now, the problem is telling us that
$
30
is equal to the expression above.
Therefore,
2/3
T
=
30
=>
6
5
⋅
5
6
⋅
T
=
6
5
⋅
30
1
=>
1
⋅
T
=
6
5
⋅
30
1
=>
T
=
$
36
3/8 = 0,375
0,375 * 100% = 37,5 %
|x＋8|=5
then x+8= 5 or -5
then x= -3 or -13
Yes, a quadratic model does exist and its equation is f(x)=4x^2
