Answer:
1.72973 oz/serving. Perhaps round to 1.73 oz, although there is only 1 sig fig in "4-pound bag." But the problem states "exactly."
Step-by-step explanation:
We want oz/serving, so let's convert the pounds of rice to total ounces of rice:
We are told that 16 oz = 1 pound. Make that a conversion factor: (16 oz/1 pound)
(4 pounds)*((16 oz/1 pound) = 64 ounces
We are told that 4 pounds (64 ounces) makes 37 servings. So:
(64 ounces)/(37 servings) = 1.72973 oz/serving
.21 as a percentage is 21%
You can divide 7.98 by 21 then multiply by 100 which gives you an answer of 38.

Explanation:
Set up two equations
2
x
+
2
y
=
54
x
×
y
=
176
Solving the first equation for x
2
x
+

y
−
2
y
=

−
2
y
this gives
2
x
=
54
−
2
y
Divide both sides by 2
(
2
x

)
=

This gives.
x
=

−
y
putting this value into the second equation gives.

y
=
176
multiplying across the parenthesis gives

y
−
y

=
176
subtracting 176 from both sides gives
