1. A fundraising dinner was planned. People will pay $20 per person to attend. The costs of this event are $12 per person for the
meals and $100 for entertainment. The group wants to raise $500 for charity after expenses. Write and solve an equation to find
out how many people will need to attend the dinner to meet the goal.

2 (3 + 10)+( (3 + 2)^2) = (6+20) + (5 x 5)= 26+ 25 =51

51 x 20 = 1020

51 x 12 = 612

1020-612 =408

408-100=308

Step-by-step explanation:

You can do this yourself if you work out numbers that equal a x b  = 1000 12 x b= 400 . once this makes sense, you cna work this out yourself.  1000-400=600 , 600-100=500 where a is the final total of the equation and represents total guests. Number 12 would be needed to represent costs only after total found. Where 100 is subtracted we see 500 is the £500 profit/revenue of £1000. or $

The answer shows that even when working in tens this cannot be simplified it needs to work in hundreds. ie) (2(5x5)) x (5x2)) =100 x 10 =1000

answer:   35 % is the probability of a late departure or an early arrival.

step-by-step explanation:

let l represents the late departure and e represents the early departure.

then, according to the question,

p(l) = 12 %,   p(e) = 27 % and = 4 %

and, we have to find out,

but, we know that,

which is the required equation that will use to find the probability of a late departure or an early departure.

therefore,   the probability of a late departure or an early arrival =   35 %
