Answer:
Step-by-step explanation:
The question is not complete, i think the correct question is:
Kareem and Kira each opened a savings account today. Kareem opened his account with a starting amount of $770, and he is going to deposit $30 per month. Kira opened her account with a starting amount of $935, and she is going to deposit $45 per month. Let x be the number of months after today
Let us assume that each acre of land on Mars cost $107.
a) For Kareem account, she started with $770 and would deposit $30 per month. Let y represent the money deposited after x month. This can be represented by the equation:
y = 770 + 30x
Since each acre cost $107, 10 acre would cost $1070. Therefore $1070 is needed to be saved. To find the number of months, substitute y = 1070 and solve. Therefore:
1070 = 770 + 30x
1070 - 770 = 30x
30 x = 300
x = 300/30
x = 10
It would take 10 months for Kareem to buy 10 acres of land
b) For Kira account, she started with $935 and would deposit $45 per month. This can be represented by the equation:
y = 935 + 45x
Since each acre cost $107, 10 acre would cost $1070. Therefore $1070 is needed to be saved. To find the number of months, substitute y = 1070 and solve. Therefore:
1070 = 935 + 45x
1070 - 935 = 45x
45 x = 135
x = 3
It would take 3 months for Kira to buy 10 acres of land
