used in July
A. 3.500 + 0.15. 3,500
B. 3,500 +0.15
»
C. 3,500 - (1 - 0.15)
D. 3,500 - (1.15)
E. 3,500. (1 + 0.15)

A. 3.500 + 0.15. 3,500

E. 3,500. (1 + 0.15)

Step-by-step explanation:

Gallons of water used in June = 3,500 gallons

In July, they used 15% more water

Water used in July = 3,500 + 15% of 3,500

= 3,500 + 0.15 * 3500

A. 3.500 + 0.15. 3,500

E. 3,500. (1 + 0.15)

= 3,500 * 1 + 3,500 * 3,500

= 3,500 + 0.15 * 3500
