Question 430074
the system of equations is


4p + 3c = 16.50


5p + 7c = 32.00


solving by elimination


1st eqn times -5 ___ -20p - 15c = -82.50


2nd eqn times 4 ___ 20p + 28c = 128.00


adding eqns (to eliminate p) ___ 13c = 45.50 ___ c = 3.50


substituting (to find p) ___ 4p + 3(3.50) = 16.50 ___ 4p = 6.00 ___ p = 1.50
