6 + y × 9 (the x is a times sign btw)
Answer:
Dale invested in fund B $8,000
Step-by-step explanation:
We can arrange the given information into the nex equation:
4000*5% + x*2% = (4000+x)*3%
4000*0.05 + 0.02x = 4000*0.03 + 0.03x
200 + 0.02x = 120 + 0.03x
200 - 120 = 0.03x - 0.02x
80 = 0.01x
x = 80/0.01
x = 8,000 He invested in fund B.
