Answer:
Tom invested 35.8% of$400000 = $143,200
Step-by-step explanation:
100%-35.4%-28.8%= 35.8%
Multiply 35.8 % (0.358) x $400,000 = $143,200.
Check work:
400,000 x 35.4% = $141,600
400,000x 28.8% = $115,200
Add all of the totals together:
141,600 + 115,200 + 143,200 = $400,000
Answer: 14 dimes and 8 quarters
<u>Step-by-step explanation:</u>
dimes ($0.10): x + 6
quarters ($0.25): x
Cost*quantity of dimes + Cost*quantity of quarters = Total value
0.10(x + 6) + x(0.25) = 3.40
0.10x + 0.60 + 0.25x = 3.40
0.35x + 0.60 = 3.40
<u> -0.60 </u> <u>-0.60 </u>
0.35x = 2.80
<u>÷0.35 </u> <u>÷0.35 </u>
x = 8
dimes: x + 6 = 8 + 6 = 14
