Tomtit [17]

Answer:

Norton's

Step-by-step explanation:

Suppose that the down payment of Mazzeo's store = 1/3 on all installment purchases

Whereas Norton's depot required 30% down payment on installment purchases.

1/3 is fractional value of 33.33%.

therefore, Norton's Store's down payment rate is lower than that of Mazzeo's store.

Solve the quadratic equation.<br>m^2/15 -3 = 2

Radda [10]

The answer is $5 \sqrt{3}$

<h3>Explanation :</h3>

$\frac{ {m}^{2} }{15} - 3 = 2$

$\frac{ {m}^{2} }{15} = 2 + 3$

$\frac{ {m}^{2} }{15} = 5$

${m}^{2} = 5 \times 15$

${m}^{2} = 75$

$m = \sqrt{75}$

$m = \sqrt{25 \times 3}$

$m = \sqrt{25} \times \sqrt{3}$

$m = 5 \sqrt{3}$
