Step-by-step explanation:
The simple way to do this is shown below:
Since two tires cost $74, you know that if you multiply that by two, you'll get your four.
74 x 2 = 148
<em>Four tires will cost you $148</em>
Most likely in millilitres, kilolitres is too large for a small cup, and the other measurements are for mass
"5 times a sum of 12 and a number is 80" translates to the next equasion:
5 x (12+a) = 80
Now we just have to solve it to find the value of a.

The unknown number is 4.
D is the right answer.
