The answer is
5q/2 or q×5/2
The unit rate is 5 1/3 grams per serving.
To find the unit rate, we can use the rule of three. If 4 grams are equivalent to 3/4 serving, how much grams would be 1 serving? Therefore, the unit rate is 5 1/3 grams per servin
To find the scale, first and foremost you should convert the length to cm:
3 meters = 300 cm, hence the scale of the model is 10/300 = 1/30
X=soy beans
y= wheat
x= 5y (because soy beans cost five times as much as wheat)
4.7x+2.4y= $51.80
Substitute x=5y
4.7(5y)+2.4y=51.80
23.5y+2.4y=51.80
25.9y=51.80
Divide both sides by 25.9
y=$2 cost of wheat per pound
x= 5y
=5(2)
=$10 cost of soy beans per pound
Check:
4.7x+2.4y= $51.80
4.7(10)+2.4(2)=51.80
47.0+4.80=51.80
51.80=51.80
Hope this helps! :)
