Answer:
The interest is $35 so it ends up costing her $70
Step-by-step explanation:
If you set you the equations such as 3c+5w=23 and 6c+2w=20 and then solve the first equation for c, you get c= (23-5w)/3 Taking that equation and substituting it for 'c' in the second equation (so the second equation becomes: 6((23-5w)/3)+2w=20 ) you get w=3.25 If you plug that back into your first equation (so it now becomes: 3c+5(3.25)=23 ) you get c=2.25 So the answer would be walnuts cost $3.25 per lb and choc. chips cost $2.25 per lb.
The formula for finding the area of a triangle is: base*height*1/2
So, if we use this information....
4.2*5.5*1/2=11.55
Area=11.55
Answer:
78 laundries
$0.25
Step-by-step explanation:
If the box contains 195 scoops and at once he uses 2 1/2 you have to divide 195 by 2 1/2 and you get 78.
How much is he paying for each load? you have to find the unit rate. The box costs $19.99 he can do 78 laundries at once so you divide the money by the quantity or in other words $19.99 by 78 and get 0.2562820512820513, since we are talking about money we use only the firs two decimals, so he pays $0.25 per load of laundry.
