I think the right answer is D. 8x+8;
This is because Frank possesses X stamps while Chris has 8 plus 7 times the number of stamps Frank holds, making the total 8 + 7x (which is 7 times Frank's amount), so when you add Frank's stamps (x) to 8 + 7x, it results in 8 + 8x.
I hope this was helpful!
Assuming the cost of 1 liter of milk is x$
and the cost of 1 loaf of bread is y$
Based on the information provided
the equations are 333x + 555y = 11
and 444x + 444y = 10
By subtracting these expressions,
we derive
(333x + 555y = 11) * 444
(444x + 444y = 10) * 333
(-) (-) (-)
147852x + 246420y = 4884
147852x + 147852y = 3330
(-) (-) (-)
------------------------------
98568y = 1554
y = 1554/98568
= 0.0157$
= 0.02$
Cost of 1 loaf of bread is 2 cents
Substituting the value of y back in
333x + 555*0.0157 = 11333x + 8.7135 = 11333x = 2.2865x = 2.2865/333x = 0.00068$ = 0.01$
Cost of 1 liter of milk = 1 cent

It's clear that
[volume of a rectangular prism]=L*W*H
<span>Among the options provided, the highest is 100
</span>100>10
100>20
100>60
100>50
V=L*W*H
with V=100 in³ and L=100 in
100 in³=100*W*H----------> W*H=1
<span>Thus, to achieve a maximum length of 100, the multiplication of width and height must equal 1.
</span>
The response is
the option A) 100
