Step-by-step explanation:
Let x be the number of chocolates in the first jar, then
x ← number of chocolates in second jar and
x + 90 ← number of chocolates in the third jar
The second jar also contains one half the chocolates in the third jar, thus
Equating chocolates in second jar
x = (x + 90) = x + 45
Multiply both sides by 10 to clear the fractions
8x = 5x + 450 ( subtract 5x from both sides )
3x = 450 ( divide both sides by 3 )
x = 150
and × 150 = 120
Number of chocolates in second jar = 120
Answer:
The dogs will eat <u>140 ounces</u> of food in 5 days.
Step-by-step explanation:

Now, to get the pounds of food dogs eat on 5 days we multiply unit rate of per day by 5:
Now, to get the ounces of food dogs will eat in 5 days we convert the pounds into ounces by using conversion factor:
<em /><em />
Therefore, the dogs will eat 140 ounces of food in 5 days.
