Hope this is what you were looking for:)
Hello there. =)
<span>Ann is grouping 38 rocks .she can put them into groups of 10 rocks or as single rocks. what are the different way Ann can group the rocks?
</span><span>2 groups of 19</span>
H(t) = f(t) - g(t)
= 500(1.2)^t - 380(1.15)^t
Taking out the greatest common factor, which is 20:
= 20[(25)(1.2)^t - (19)(1.15)^t]
This is the third choice.
Note that you cannot subtract the bases of the exponents, for example (1.2^t - 1.15^t) cannot be simplified into something like 0.05^t.
8% of $82.50 is $6.60 so 82.50 + 6.60 would equal $89.10 as the total
The actual quotient will be greater than 10 because 60 divided by 5 is 12, so the answer will be between 10 and 12, so it will be greater than 10
