Answer:
B and C
Step-by-step explanation:
the answer is 2,220
you first aline 185 × 12 like so 185
× 12
then you need to multiply everything
If two numbers are a and b
a+b=56
a-b=16
2a=76
a=38
b=22
the product is a*b=38*22=836
6.5 x 10 to the 3rd power
remember the base must be less than 10 and greather or equal to 1
One company wants $10 per 3.5 hours, so they want 10 / 3.5 ≈ 2,86 dollars per hour (after rounding to the closest hundreths).
Second company wants $1.25 per half an hour, so they want 2 * 1,25 = 2,50 dollars per hour.
The unit rate is 2,86:2,50
