So, monthly expenses = 1120+600+140/12 = 1731.667 = 1732
and his monthly income = 840×2 = 1680
so there is a surplus of 52
and I guess the answer will be first one by options you gave !!
Answer:
75 km
Step-by-step explanation:
(50km/h)(1.5h) =<em> 75km</em>
The total amount that Chang will received from his wages is the product of his hourly wage times the number of hours he has worked (n). His total savings should not be less than $125. The equation that best describes the situation is,
45 + 7n ≥ 125
Solving for n in the inequality gives an answer of n≥11.42 hours. Thus, he needs to work for at least 12 hours.
