2.45kg
First you calculate the price per kg as follows:
If it’s $20 for 12.25 kg, the price per kg is $20/12.25=$1.63 per kg
If you have $4, you can figure out what weight you can get by taking $4/the price per kg, so $4/$1.63, which is 2.45 kg.
a=m-2b
I believe is the correct answer
A bajillion sorry if I'm wrong
Its eliminating. You will need to make the conditions on each side just as much alike as possible in the two equations for simple thought method
90°=X+3X+10
X + 3X+ 10=90
4X+10=90
90-10 =80
4X=80
80/4=20
X=20
D. 913 people
Explanation: You add Tuesday and Wednesday’s attendance together since the problem asks for combined (21,827 + 18,632 = 40,459) and then subtract that from Saturday’s attendance (41,372-40,459 = 913).
