A+180°+B+C+D

180°+90°

In 2003 Exxon Mobil received a contract from the government worth $756,733 while Aerospace received a contract from the governme

lutik1710 [3]

The combined total of their contracts is $1,296,250

<h3>How to determine the combined total?</h3>

The values of the contracts are given as:

Exxon Mobil= $756,733
Aerospace = $539,517

The combined total is represented as:

Total = Exxon Mobil + Aerospace

Substitute known values

Total = $756,733 + $539,517

Evaluate the sum

Total = $1,296,250

Hence, the combined total of their contracts is $1,296,250
