Answer:
-6
Step-by-step explanation:
We can use the slope formula
m = ( y2-y1)/(x2-x1)
= ( 8-2)/(3-4)
= 6/-1
= -6
Answer:
Camels has to pay $42 more as interest
Step-by-step explanation:
We are given that Carmela borrows $400 and will pay 5.25% yearly simple interest.
Principal = $400
Rate of interest = 5.25%
Time = 2 years
Formula :
So,
SI=42
She borrows the money for 4 years instead of 2 years,
So,
SI=84
Difference in interests = 84-42 = 42
Hence Camels has to pay $42 more as interest
Answer:
C) $3.77
Step-by-step explanation:
- Turn 30% into 0.30 by moving the decimal point (percentage sign) 2 places to the left.
- To solve 30% of $2.90 → 0.30 x 2.90 = 0.87
- Finally $2.90 + $0.87 = $3.77
The two equations are: 3x + 2y = 36.50 (I)2x + 5y = 50 (II)Eliminating x from the two equations by subtraction:first we multiply equation I by 2 and equation II by 36x + 4y = 736x + 15y = 150Subtracting the two,-11y = -77y = 7He earns $7 at the coffee cartSubstituting y into equation I,3x + 14 = 36.5x = $7.50Therefore, he earns a greater wage of $7.50 at the library, the answer is C
