Answer:
40 chocolates
Step-by-step explanation:
30% *C=12
0.3*C=12
C=40
To the nearest what the nearest ten is 360,000 nearest ten thousand 400,000
Quarter is $0.25
Dollar is just $1
x is amount of quarters
y is amount of dollar coins
Two equations we know
0.25x+1y=10.75 and
x+y=22
solve both for y
0.25x+1y=10.75
y=10.75-0.25x
x+y=22
y=22-x
set them equal
22-x= (y) =10.75-0.25x
11.25=0.75x
x=15 quarters
then put x=15 into either equation and now solve for y
x+y=22
15+y=22
y=7 dollar coins
