Question: * 1.7.20 (was 1.2.30). Explain how you set up and solved an equation for the problem. Include your equation and the reasoning you used to develop the equation. Problem (note that this statement is for instructor reference; the full statement was in your text) million to lend at 19% or 16%, max lent at 16% to average 18%.

YYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYY

Your solution:

If you multiply 1 million by 18 %, 16% and 19 % you get

180,000

160,000

190,000 respectively and this means that if you gave everyone a loan at 16% you would be 20,000 short of your quota. IF you gave everyone a loan at 19% you would be 10,000 over your quota so this means that your equation should be

x = money loaned out at 16%

then 180,000 - x = money loaned out at 19%

.16x +.19(1,000,000) - x = 180,000

160,000x + 190,000 - x = 180,000 combine like terms

159999x + 190,000 = 180,000

159999x = -10,000

x = - 6 % which means 6 % of the loans must be at 19%
