Answer:
$50.1
Step-by-step explanation:
If you plug 40 in for x in the equation y=0.94x+12.5 then you should get 50.1 for y.
Rewrite the fractions so they have a common denominator
3/4 = 15/20
Now add:
4 15/20 + 7 11/20 = 11 26/20
26/20 simplifies to 1 3/10
11 + 1 3/10 = 12 3/10 total minutes
To do this, firstly convert the fraction to a decimal, then multiply it by 100 (the same way you would to get your percentage in a test.).
16/75 = 0.213 to 3sf
Then multiplying that we get 16/75 is 21.3%
