Caleb bought groceries and paid

lutik1710 [3]

Answer:

Price of Caleb's groceries before tax= $6.4

Step-by-step explanation:

Let price of groceries before tax be = $ $x$

Sales tax % = 2.5%

Sales tax applied = $2.5\% \ of\ x = \frac{25}{100}\times x = \frac{25}{100} x$

Actual sales tax paid = $1.60

∴ $\frac{25}{100}x=1.60$

Multiplying both sides by 100.

$100\times \frac{25}{100}x=1.60\times 100$

$25x=160$

Dividing both sides by 25.

$\frac{25x}{25}=\frac{160}{25}$

$x=6.4$

∴ Price of groceries before tax= $6.4

At a certain college, the ratio of men to women is 6 to 5. If there are 1,500 men, how many women are there?

Fed [463]

Let 6x represent the men

5x represents the women

The ratio of men to women is 6 to 5 or 6/5

6x / 5x = 1500/ W where W is the number of women

6/5 = 1500/W

W = 1250 women
