He got 22/25 questions right because
if you put X as the number of questions he got right out of 25 and equal it to 88 out of 100 you can cross multiply to get X
x/25=88/100
100x=25×88
25×88=2200
100x=2200
divide 100 on both sides
therefore
2200/100= 22
hope this helps
Let x be the amount he invests at 6%
1280 = 0.06x + 0.07(20000 - x)
1280 = 0.06x + 1400 - 0.07x
1280 - 1400 = -0.01x
-120 / -0.01 = x
x = 12000
Therefore, he invests $12,000 at 6% and $8,000 at 7%
