Linear Question

Question

A total of $68,000 is to be​ invested, some in bonds and some in certificates of deposit​ (CDs). If the amount invested in bonds is to exceed that in CDs by $1,000, how much will be invested in each type of​ investment?

Answer 1

B + C = 68000

B = C + 1000

Substitution: C + 1000 + C = 68000

2C = 67000.

Can you solve for C and then for B?

Could also split the 68000 in half and add/substract half of 1000 to the result.
