The price of one hot dog was $1.65
<u>Step-by-step explanation:</u>
Given that each of the four brothers bought two hotdogs and a packet of chips each.
Total number of hotdogs they bought=4*2 =8
Total bags of chips they bought= 4
price of a bag of chips=$1.25
Total price of items=$18.2
let the price of a hotdog=x
then
8x+5=18.2
8x=18.2-5
8x=13.2
x=13.2/8
=1.65
The price of one hotdog=$1.65
Answer:
1200 ml per hour
Step-by-step explanation:
To compute what rate is 300 ml over 15 mins as a rate of ml per hour, we do a rule of 3, using a variable x as that amount of ml we don't know yet. We should have everything in the same units, so instead of writing 1 hour we write 60 minutes:
Now we solve for x:
And so, now that we know the value of x, the rate we wanted to find is
Which is just 1200 ml per hour.
