Sold DVD for 50% more of the purchase price of $12
so 12 + 50/100 (12)
=12+6
18

So customer will pay 7% tax on $18

Hence he will pay 18 (1.07)$
= $19.26

Hope this helps

OMG PLEASE HELP ME ASAP!!!!!!! A local charity sponsors a 5K race to raise money. It receives $55 per race entry and $10,000 in
Dominik [7]
Start with how much profit they are making off each race entry. People pay $55 to race, but $15 of that is expenses so they are only profiting $40 for each entry. Now write one side of the equality. They start with $10,000 in donations, and then have a $40 profit for each race entry. So 10,000+40x. X will represent the unknown number of race entries. What do we want that expression to be equal to? We want 10000+40x>55000. It can also be greater than or equal to, not just greater than. Solve for x. Subtract 10000 from each side resulting in 40x>45000. Divide each side by 40 to solve for x. X>1125. X needs to bbe greater than or equal to 1125. If there are 1125 race entries, the charity will profit exactly $55000, so the lowest number of race entries is 1125

Air has a density of 0.001226 g/mL. What volume of air would have a mass of 1.0 lb? A. 2.7 mL B. 815.6 mL C. 37 mL D. 3.7 × 102
Andre45 [30]

Answer:

Volume = 3.7\ * 10^2\ L

Step-by-step explanation:

Given

Density = 0.001226 g/mL

Mass = 1.0\ lb

Required

Determine the volume of air

Density is calculated using:

Density = \frac{Mass}{Volume}

Substitute values for Density and Mass

0.001226 g/mL = \frac{1.0\ lb}{Volume}

Convert lb to grams

0.001226 g/mL = \frac{1.0 * 453.592\ g}{Volume}

0.001226 g/mL = \frac{453.592\ g}{Volume}

Solve for Volume

Volume = \frac{453.592\ g}{0.001226 g/mL}

Volume = 369977.161501\ mL

Convert mL to L

Volume = 369977.161501\ L * 0.001

Volume = 369.977161501\ L

Represent using scientific notation

Volume = 3.69977161501\ * 10^2\ L

Approximate

Volume = 3.7\ * 10^2\ L
