Alocal charity sponsors a 5k race to raise money . it receives $55 per race entry and 10,000 in donations, but it must spend $15 per race entry to cover the cost of the race. write and solve an inequality to determine the number of race entries the charity needs to raise at least 55,000.

let the number of race entries be x

55x+10,000-15x =55000

55x-15x=55000-10000

40x=45000

x = 500

It must receive 500 race entries.

Step-by-step explanation:

well we know there are 4 clubs in 52 cards so it’s replaced so it should be 3/51

step-by-step explanation:

the answer is:

the correct option:

b.

to solve the problem, we need to remember how to operate to simplify exponential expressions using the logarithms.

we are given the equation:

then, using placing logarith with base 7 on both sides of the equation, we have:

so, rounding the obtained result to two decimal places (nearest hundreth), we have:

hence, we have that the correct option:

b.

have a nice day!
