Asmall child is at a candy store, eager to spend his $1 allowance on candy. his two favorite candies are priced at $0.05 and $0.10, respectively. if the child is intent on spending his entire allowance on candy, which of the following represents a standard form equation that describes this situation?
a. 0.05x 0.10y=1.00
b. 0.10x-0.05y=1.00
c. 5x 10y=100.00
d. x 2y=20.00

First step is to get rid of the square root. remember that a square root is the same as raising to the (1/2) power. see below: multiply exponents per exponent rules to get: remember you subtract exponents from the denominator and add exponents in the numerator so: simplify further: so a is the correct choice. if you don't understand this google exponent rules and it will you understand. look at the image results.
