Step One
Convert miles to km. The conversion constant is 1.6 km / mile
19 miles * 1.6 km/mile = 30.4 km Notice the miles cancel.
Step Two
Convert the gallons to liters.
This is the sticky part of the question. Where are you? The conversion factor is different in Canada or Great Britain that it is in the United States. If you are not in the US use 4.5 otherwise 1 gallon has 3.78 L in it if it is a US gallon
30.4 km / 3.78 L = 8.04 km per Liter using a US Gallon.
30.4 km / 4.5 L = 6.76 km / Liter using an Imperial Gallon which not used in either Canada or Great Britain. Imperial Gallons are obsolete.
Since you have 4 people total splitting the money, you can find the total amount made in the two months by: 184(4)=736
Since you want the total profit in the second month, subtract the total amount by the profit in the first month: 736-438=298
So the answer is $298
Answer: 7bb +19 ll ≥210
Step-by-step explanation:
Hi, to answer this question we have to write an inequality:
The product of the number of hours he works babysitting (bb) and the amount he earns per hour (7); plus The product of the number of hours he works lifeguarding (ll) and the amount he earns per hour 19; must be higher or equal to the amount he must earn this week (210)
Mathematically speaking:
7 bb + 19 ll ≥210
Answer:
14b
Step-by-step explanation:
