Nina saves 40% of her summer job earnings for college. This summer, she earned $200 more than last summer, and she saved $900. W
beks73 [17]

Answer:

(900 ÷ 4) x 10 -200 = 2050 And this will equal last Summer's earnings

Step-by-step explanation:

So we know that 900$ is equal to 40% and that we can simplify this

900 ÷  4 = 225

40% ÷  4 = 10%

Therefore:

225 = 10% and

2250 = 100% of earnings

Joyce's mother buys some shares of Company A on Day 0.
antoniya [11.8K]

Answer:

(i) 4000

(ii) $5.00

Step-by-step explanation:

Let no. of shares of Company A be X

Let share price of Company B on Day 7 be $y

Share price of Company B on Day 12 = $(y-0.50)

(i)

Consider Day 7:

4.60x - 2000y = 7400................ (1)

Consider Day 12:

4.80x - 5000(y-0.50) = -5800

4.80x - 5000y + 2500 = -5800

4.80x - 5000y = -8300............... (2)

(1)*2.5:

11.5x - 5000y = 18500................. (3)

(3)-(2):

11.5x - 4.80x - 5000y + 5000y = 18500 + 8300

6.70x = 26800

x = 4000

(ii)

Sub. x = 4000 into (1):

4.60(4000) - 2000y = 7400

-2000y = 7400 - 18400

-2000y = -11000

y = 5.5

Share price of Company B on Day 12

= 5.50 - 0.50

= $5.00

Thx, 5 star and brainliest for first
Anastaziya [24]

In calculating this, you would have to find the unit price first.

$13 per 3 1/4 yards is also equal to $4 per yard.

Then you would have to find out the other ones' unit prices.

a) $16 per 4 2/3 yards is equal to around $2.82 per yard, so <u>No</u>

b) $11 per 2 3/4 yards is equal to $4 per yard, so <u>Yes</u>

c) $26 per 6 1/2 yards is equal to $4 per yard, so <u>Yes</u>

I solved these by dividing the amount of money by the amount of string.
