First work out the unit price:
16-oz $1.76/16=$0.11 per oz
20-oz $2.40/20=$0.12 per oz
From this the 16-oz bottle is better value for money than the 20-oz because the unit price is lower.
I don’t have any statements in front of me to make an answer selection, but I hope this helps.
Speed = distance / time
3 hours 45 minutes = 3.75 hours
80 = distance / 3.75
distance = 80 * 3.75 = 300 kms Answer
A) 6+x+4 = 2+3x+4
10+x = 3x+6
10 = 2x+6
4 = 2x
x = 4/2
x = 2
B)
6 * (x+4) = 2 *(3x+4) =
6x+24 = 6x+8
there is no solution for part B
let
x-------> walnuts that Mario eats in a week
y-------> walnuts that Yolanda eats in a week
we know that
x=2y-------> equation 1
y=6*7-------> y=42 walnuts
substitute the value of y in equation 1
so
x=2*42-----> x=84 walnuts
therefore
the answer is
Mario eat in a week 84 walnuts
