Francesca had 20 dollars to spend on 3 gifts. She spent 8 1 4 dollars on gift A and 4 4 5 dollars on gift B. How much money did

Karo-lina-s [1.5K]

Answer:

Francesca had $\$\frac{139}{20} \ \ OR \ \ \$6\frac{19}{20}$ money left for gift C.

Step-by-step explanation:

Given:

Total money to spent on gift = $20

Money Spent on gift A = $\$ 8\frac{1}{4}$

$\$ 8\frac{1}{4}$ can Rewritten as $\$\frac{33}{4}$

Money Spent on gift A = $\$\frac{33}{4}$

Money Spent on gift B = $\$ 4\frac{4}{5}$

$\$ 4\frac{4}{5}$ can Rewritten as $\$\frac{24}{5}$

Money Spent on gift B = $\$\frac{24}{5}$

We need To find the Money left for gift C.

Solution:

Money left for gift C can be calculated by subtracting Money Spent on gift A and Money Spent on gift B with Total Money spent on gifts.

Framing in equation form we get;

Money left for gift C = $20-\frac{33}{4}-\frac{24}{5}$

Now taking LCM for making the denominator common we get;

Money left for gift C = $\frac{20\times 20}{20}-\frac{33\times5}{4\times5}-\frac{24\times4}{5\times4}= \frac{400}{20}-\frac{165}{20}-\frac{96}{20}=\frac{400-165-96}{20} = \$\frac{139}{20} \ \ OR \ \ \$6\frac{19}{20}$

Hence Francesca had $\$\frac{139}{20} \ \ OR \ \ \$6\frac{19}{20}$ money left for gift C.

25% offer two honors classes and 5% offer four honors classes. Add these together:

25 + 5

= 30
