Answer:
The correct answer is 11 weeks
Step-by-step explanation:
The equation for this case is:
435 + 25 x = 875 - 15 x => 25 x + 15 x = 875 - 435 => 40 x = 440
x = 440 / 40 = 11
x = 11 weeks
God with you!!!
They both have the same amount of money in the bank in 11 weeks.
The distribution of weights to the variables involved that establishes the equilibrium in the calculation is referred to as a result.
Let x be the number of weeks and y be the amount of balance in the account.
Nancy started the year with $435 in the bank and is saving $25 a week. Then the equation will be
y = 25x + 435 ...1
Shane started with $875 and is spending $15 a week. Then the equation will be
y = -15x + 875 ...2
From equations 1 and 2, then the number of weeks will be
25x + 435 = -15x + 875
25x + 15x = 875 - 435
40x = 440
x = 440 / 40
x = 11
They both have the same amount of money in the bank in 11 weeks.
