V = IR...divide both sides by I
V/I = R

a = hours worked by the first mechanic
b = hours worked by the second mechanic.
since the first mechanic charges $55 per hour, then for "a" hours that'd be a total of 55*a or 55a, likewise, for the second mechanic that'd be a total charge of 80*b or 80b.
we know all hours combined are 15, so then a + b = 15.
we also know that all charges combined are $950, so 55a + 80b = 950.
Answer:
d = 100
Step-by-step explanation:
0.1d + 0.25(10) = 12.5
0.1d + 2.5 = 12.5
0.1d + 2.5 - 2.5 = 12.5 - 2.5
0.1d = 10
0.1d × 10 = 10 × 10
d = 100
