Answer:
Number of girls in the school is 354.
Step-by-step explanation:
Total number of members = Total students + total number of staff members
= 864 +80
=944
Given out of total members are boys.
We have to determine the number of girls in the school.
First we find the number of boys then subtract it from total number of members.
Number of boys = of total number of member
Thus, number of boys are 590
Thus, number of girls = total number of members - total number of boys
= 944 - 590
= 354
Thus, Number of girls in the school is 354.
Answer:
4.1 years.
Step-by-step explanation:
We have been given that The Lisbon’s new heat pump cost $4,500. They bought it to replace their old furnace and air conditioner which cost about $2,800 a year to run. The heat pump will save them approximately 39% a year.
Yearly cost was 2800 at first and the pump will save 39% of 2800. So annual saving with new heat pump will be:
Let x be the number of years in which heat pump will pay for itself, so saving in x years will be:
Now let us equate the savings by new heat pump with cost of heat pump to find the number of years (x).
Therefore, the heat pump will pay for itself in 4.1 years.
