Answer:
Subtract 1.1j from both sides.
L = total lengh, D = number of days
L = 4D + 51 <== ur equation
after 37 days...D = 37
L = 4(37) + 51
L = 148 + 51
L = 199 miles <==
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.
