Step-by-step explanation:
Step-by-step explanation:
Below is an attachment containing the solution.
First, you need to figure out hoe many boys and girls there are.
40% = 0.4
0.4 x 20 = 8 boys
20 - 8 = 12 girls
25% of the boys have glasses
0.25 x 8 = 2 boys who wear glasses
50% of the girls have glasses
0.5 x 12 = 6 girls who wear glasses
2 + 6 = 8
8 students wear glasses
Assuming that means 1.10^t:
0.10 is for years. To get months divide by 12.
0.10/12 = 0.0083333...
And (1+0.083333...) = 1.0833333. (You will have to multiply t by 12 also to get it in terms of months)
(1.0833333)^12t
