Answer:
she attended 25 classes
Step-by-step explanation:
when you do this you subtract the annual fee of $100 from the total payment $225 which leaves you with $125 then you divide it by The fee for each class Which is $5 so you get 25 classes
Your equations would be
c+d=10
5c+6d=56 (c= # of cats, d= # of dogs) Then solve
I am using elimination and multiply the first equation by -5
-5c-5d=-50
5c+6d=56
Then eliminate
-d=-6 Divide by -1 d=6
Then solve for c
c+6=10
c=4
Hope this helps!
Answer:
Step-by-step explanation:
Formula
r = amount / time
Givens
amount = 3/10
time = 2/5
Solution
r = 3/10 // 2/5
Invert the denominator (2/5) and multiply rather than divide.
r = 3/10 * 5/2 Cancel 5 into the 10
r = 3/2 * 1/2
answer: r = 3/4 chord / hour
Answer:
10 hotdogs for $5.00 is the better deal
Step-by-step explanation:
Let's find the price of 1 hotdog if 8 hotdogs cost $4.08.
$4.08 ÷ 8 = $0.51 per hotdog
Now let's find the price of 1 hotdog if 10 hotdogs cost $5.00.
$5.00 ÷ 10 = $0.50 per hotdog
$0.50 per hotdog is slightly cheaper than $0.51 per hotdog, so 10 hotdogs for $5.00 is the better deal.
