Ответ:
July savings= $35
August savings= $ 105
Step-by-step explanation:
Let's represent her JULY savings as "x"
Let's represent her August savings with (3 * x), since she saved three times her July savings.
Her Total savings for the both months are the sum of JULY savings and AUGUST savings which is equal to $140.00
Therefore:
x + 3x = $140
4x = $140
Divide through by 4
x = $140 / 4
x = $ 35.
It means the JULY savings (x) = $35.
Let's solve for AUGUST SAVINGS:
= 3 * x
When x = $35
August Savings = 3 * $35
= $ 105
