Answer:
Mario bought five books.
Step-by-step explanation:
If Mario bought n magazines, then n is the solution of
23.85 = 12.60 + n*2.25
23.85 - 12.60 = n*2.25
11.25 = n*2.25
n = 11.25/2.25
n = 5
Answer:
£3692
Step-by-step explanation:
A = p(1 + r/n)^nt
Where,
A = future value
P = principal = £2350
r = interest rate = 4.2% = 0.042
n = number of periods = 1(annual)
t = time = 4 years
A = p(1 + r/n)^nt
= 2350(1 + 0.042/1)^1*4
= 2350(1 + 0.042)^4
= 2350(1.042)^4
= 2350(1.5789)
= 2770.42
A = £2770.42
Total years = 10
Remaining years = 10 - 4
= 6 years
Remaining 6 years
P = £2770.42
r = 4.9% = 0.049
n = 1
t = 6
A = p(1 + r/n)^nt
= 2770.42(1 + 0.049/1)^1*6
= 2770.42(1 + 0.049)^6
= 2770.42(1.049)^6
= 2770.42(1.3325)
= 3691.59
A = £3691.59
Approximately £3692
Answer:
<h2>2</h2>
Step-by-step explanation:
<h3>Let n= 4, m= -2 and j= 5</h3><h3 /><h3>(9n + 8m)/2j</h3><h3>= 9(4) + 8(-2)/2(5)</h3><h3>= 36 + (-16)/10</h3><h3>= 20/10</h3><h3>= 2</h3><h3 />
