Answer:

$2147.36

Step-by-step explanation:

The first value can be modeled by ...

b1 = 1000·(1 -0.005)^t

After 10 years, that balance is ...

b1 = 1000·0.995^10 = 951.11

The second value can be modeled by ...

b2 = 1000·(1 +0.018/2)^(2t)

After 10 years, that balance is ...

b2 = 1000·1.009^20 = 1196.25

The total of the two investments after 10 years is ...

$951.11 +1196.25 = $2147.36

A cup and saucer cost $3.10 at the local store. The cup costs $2.00 more than the saucer. How much does each cost?

AlekseyPX

Answer: cup is $2.55

Saucer $0.55

Step-by-step explanation:

Cost of cup and saucer is $3.10

Let the cup be x

And saucer be y

I.e

X+y= 3.10......equation 1

Cup which is X is $2 more than the saucer

I.e x=2+y......equation 2

Substitute for X in equation 1

(2+y)+y=3.10

2+2y=3.10

2y=3.10-2

2y=1.10

Y=1.10/2

Y=$0.55

Substitute for y in equation 2

X=2+y

X=2+0.55

X=$2.55

Therefore

The cup is $2.55

The saucer is $0.55
