Eli wants to combine 0.5 gallon of a 10% acid solution with some 35% acid solution to make a 15% acid solution. Which equation can you use to determine how many gallons of the 35% acid solution Eli should add?
a. (0.10)(0.5) + 0.35g = 0.15 (g + 0.5)
b. (0.10)(0.5) + 0.35g = 0.15 (g + 0.5) + 0.15
c. (g + 0.5) + 0.15 = 0.15(g + 0.5)
d. (0.10)(0.5)(0.35g) = 0.15(g + 0.5)

there are 70 more legs than eyes at the dog show (196 – 126 = 70). dogs have two more legs than eyes, and humans have the same number of legs as eyes. thus 70 is twice the number of dogs at the show, so the number of dogs is half of 70, which is 35. to get the number of humans, subtract 35 from 63: 63 – 35 = 28.

step-by-step explanation:

this is the formula: v = the value of investment at the end of the time period

p = the principal amount (the initial amount invested)

r = the annual interest rate

n = the annual frequency of compounding (how many times a year interest is added)

t = the number of years the money is invested
