Answer: The answers are (3). $3744, (4). $8464.50, (5). $62060.
Step-by-step explanation: The calculations are as follows :
(3) Here, P = $1200, r% = 4%, T=3 years.
Therefore, Simple Interest is given by
So, the amount of money Ben will have at the end of third summer will be
Thus, the amount is $3744.
(4) Here, P = $2700, r% = 4.5%, T=3 years.
Therefore, Simple Interest is given by
So, the amount of money Josh will have at the end of third summer will be
Thus, the amount is $8464.5
(5) Here, P = $14500, r% = 7%, T=4 years.
Therefore, Simple Interest is given by
So, the amount of money Emily will have at the end of fourth year will be
Thus, the amount is $62060.
4. $8464.50

Two lines while intersecting, form two pairs of vertical angles (see attached diagram). It is known that vertical angles have equal measures.
Thus,
- m∠1=m∠3;
- m∠2=m∠4.
Let m∠1 = x°, then m∠2 = (x+50)°.
Angles 1 and 2 are supplementary, then
x+x+50°=180°,
2x=180°-50°,
2x=130°,
x=65°
Therefore,
- m∠1=65°;
- m∠2=65°+50°=115°.
Answer: 65°, 115°, 65°, 115°

If you have 60 seconds you can multiple 10 by 6 because 10×6=60
so you also have to multiple 4 by 6
4×6=24
and because it's descending it's 100-24= 76
