6-10.

In 2009, the federal government budget was $\3.1$ trillion $(3{,}100{,}000{,}000{,}000)$. The government was looking to cut costs.

1. If it decided to cut $1\%$, how much did it cut?

Find $1\%$ of $\3.1$ trillion.

Convert $1\%$ into a decimal, then multiply that by $\3.1$ trillion.

$(0.01)(3{,}100{,}000{,}000{,}000)$

$31$ billion or $31{,}000{,}000{,}000$.

2. If the government reduced the budget by $7\%$, how much did it cut?

Find $7\%$ of $3.1$ trillion.

See part (a) for help.

3. If the government eliminated $93$ billion $(93{,}000{,}000{,}000)$ from the budget, what percentage did it cut?

$\93$ billion is what percent of $\3.1$ trillion?

Divide $\93$ billion by $3.1$ trillion.

$\frac{93,000,000,000}{3,100,000,000,000}=0.03$
Convert this decimal into a percentage.
