Question 535770
"10 more type C clamps than the total of the other types" ___ c = a + b + 10


"twice as many b clamps as type a" ___ b = 2a


"The shop produces 250 clamps per day" ___ a + b + c = 250


substituting for c ___ a + b + (a + b + 10) = 250 ___ 2a + 2b + 10 = 250


substituting for b ___ 2a + 2(2a) + 10 = 250 ___ 6a + 10 = 250 ___ a = 40


use the value of a to find b and then c
