Emma borrowed $312 from her sister. She determines that she can pay her back in thirteen months worth of allowance. What effect
gulaghasi [49]

Answer:

This repayment will ultimately reduce her monthly bank account balance

Step-by-step explanation:

This repayment will ultimately reduce her monthly bank account balance. That is because the steady monthly income that Emma would normally receive to her bank account will be taken out of her account and sent to her sister's account. This will continue to occur for 13 months until Emma pays back the $312 that she borrowed from her sister. Once the 13 months are over and her debt is paid, her monthly bank balance will return to normal and begin increasing as her income payments get deposited.

2) Two big bags of sugar plus one small bag of flour add up to a total of 12 kg.
alisha [4.7K]

Answer:

It's just a simultaneous equation

Step-by-step explanation:

Let a big bag of sugar = x

Let a small bag of flour = y

x+x+y = 12kg

2x+y = 12kg ... 1

x-y = 2kg ... 2

Add 1 and 2

2x+y = 12

+

<u> </u><u> </u><u>x</u><u> </u><u>-</u><u>y</u><u> </u><u>=</u><u> </u><u> </u><u>2</u>

3x = 14

x = 14/3 = <u>4.66</u>

Substitute value of x into 1

2(4.66)+y = 12

9.333 + y = 12

12 - 9.333= 12

y = <u>2</u><u>.</u><u>6</u><u>6</u>

Hope you understand it

And I hope my answer was of help to you.
