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
Answer:
61.716 seconds (62 if round up is needed)
Step-by-step explanation:
36 / 7 = 5.143
5.143 * 12 = 61.716
You can't find the exact value of y, but you can find y in terms of x!
Adding 3y and subtracting 8 from both sides, we have:
2x-3y+3y-8=8+3y-8
2x-8=3y
Dividing by 3, we see that y=(2x-8)/3. This is the simplest form we can find for y.
