There are nine boxes in each pack. Garth bought 2 packs, all together containing 18 boxes. So 18÷2=9. Rico bought 4 packs, so 36 boxes divided by 4 equals 9. And so on. Your answer is 9 boxes = 1 pack.
ANSWER:
Total cost for Diego to attend university,
$11,850 + $10,645 + $1,780 + $1,864 + 1,602
Now for 4 years, we have to multiply it by 4.
Given that,
the two numbers are consecutive
The two numbers are
x and x + 1
Sum of the numbers = 81
x + (x + 1) = 81
x + x + 1 = 81
2x = 81 - 1
2x = 80
x = 80/2
x = 40
Therefore, <em>the two numbers are</em> x = 40 and x + 1 = 41
