Hello!
We need to find a denominator that both fractions can be. /63 works perfectly because 7x9 = 63. 3 x 9 = 27, and 4 x 7 = 28. Since 28/63 is bigger than 27/63, ramundus puts more money into car expenses.
22% is 0.22 in decimal form
0.22×45= $9.90 markdown so 45-9.90= $35.10 is the sales price
Answer: 15
REMEMBER: The mode is the value that appears most frequently in a data set.
We have two unknowns from the equation therefore, two equations are needed. These equations are:
<span>
3x + y = 9
y = –4x +10
To solve for y, we first substitute the second equation to the first one.
</span>3x + –4x +10<span>= 9
</span><span>x = 1
We substitute the value of x to either of the equations and solve for y.
</span>y = –4(1) +<span>10
</span><span>y = 6
</span>
Answer:
The answer is D - 3.786x10^7
