44/2.5 = x
x= 17.60
Answer:
a. $17.83
b. $82.17
Step-by-step explanation:
a.
We need to find total cost of all the items.
2 package of pencil for 1.98 each: Total = 1.98 * 2 = 3.96
1 binder for 7.69: Total = 7.69
1 divider for 2.69: Total = 2.69
1 pencil box for 3.49: Total = 3.49
We sum all of these to get:
3.96 + 7.69 + 2.69 + 3.49 = $17.83
b.
She only spent 17.83 and she had 100 dollars. So we subtract amount spent (17.83) from total (100) to get remaining balance.
100 - 17.83 = $82.17
When you have ratios, and some unknowns, you can create complex fractions from them. Bring them to the same denominator, and solve for x.
Example - we have this proportion:
2-x
5-45
And we can change it into fraction:
\frac{2}{5}=\frac{x}{45}
\frac{2*9}{5*9}=\frac{x}{45}
\frac{18}{45}=\frac{x}{45}
18=x
In case of more complex fractions it may come in handy.
