What's the scale factor?​

The scale factor is approximately 1.67

Step-by-step explanation:

30 × 1.67 = 50.1

50.1 ≈ 50

Incase you needed to know; y = 30 and x = 9

Kyle invested 5,800 at 10% and 5,400 at 7%.

Step-by-step explanation:

Let x be the amount Kyle invests in the 10% account.

0.1x + 0.07(11200 - x) = 958

0.1x + 784 - 0.07x = 958

0.03x = 174

x = 5800
