.50(150)+30=$105
8(32)+12 = $268
Y= kx (k being a constant)
10= k × 4 k=5/2
y= 5x/2 The answer is C.
Step-by-step explanation:
Molly ran 1/4 of a mile in 1 minute, i.e.
1/4 mile : 1 minute
Multiply both sides by 4 to get time for one mile
1 mile : 4 minutes
Multiply by 4 again to get time for 4 miles
4 miles = 4*4 = 16 minutes.
So it takes Molly 16 minutes to run four miles.
