In the state of indiana, 368,000 people lacked basic prose literacy skills. if this is 8% of the population of indiana residents aged 5 years and older, estimate the population of indiana residents aged 5 years and older.

This problem can be solved with a proportion. We know that 8% of the population is the 368,000 and we want to find the whole population.

To make the proportion, let P be the population. Left side of the equals is the group we know, right side is the whole state, the top is the portions, the bottom are the populations.

We can't have percents in the proportions, so let's convert them to fractions or decimals. Percent means "per 100". So 8% = 8 per 100 = 8 / 100 = 0.08  Similarly, 100% = 100 per 100 = 100/100 = 1

Now we cross multiply to solve.

(0.08)(P) = (1)(368000)

0.08P = 368000

P = 368000/0.08    <-- divide both sides by 0.08

P = 4600000

Thus, Indiana has a population (that's aged 5 years or older) of 4,600,000.

step-by-step explanation:

the final amount you will pay is $68.04.

the tip is determined by the pre-tax amount, so we calculate the tip based on the original bill, not after we've added sales tax.

to find the tip:

we can divide 54.00 by 100 to get 1% of 54. then we multiply that by 18.

54 / 100 = .54

.54 x 18 = 9.72

tip = 9.72$

to find the tax:

we can divide 54.00 by 100 to get 1% of 54. then we can multiply that by 8 to get 8%.

54 / 100 = .54

.54 x 8 = 4.32

tax= 4.32

now we can add the tip and tax to the bill to get our total.

54 + 9.72 + 4.32 = 68.04

total: $68.04
