Step-by-step explanation:
= 4/5 × 8 /9
We will cross multiply
= 40 × 36 / 45
= 1440 / 45
= 32
<u>Final Answer:</u>
mean = 4 sundaes
<u>Solution:</u>
each bowl of sundaes contains 3 sundaes.
- two scoops = 4 sundae bowls
- I scream = 6 sundae bowls
- dream scream = 2 sundae bowls
(plus 3, the number three represents how many sundae's there are in a bowl)
(divide it by 12, since there are 12 numbers in the data set)
Mean = (4 + 4 + 4 + 6 + 6 + 6 + 2 + 2 + 2 + 4 + 4 + 4) ÷ 12
= 48 ÷ 12 = 4
The two equations expressed in this scenario will be
y = 13x + 34
And
y = 30x
I like substitution, so let’s use that
Plug in y = 30x for y in the first equation
30x = 13x + 34
Subtract
17x = 34
x = 2
Plug in 2 for x in any equation
y = 30(2)
y = 60
It would be 2 hours and she would pay $60 dollars
