4h +8=20
Hours worked times rate paid plus 8 must equal 20
y = 0.22(12) + .99 = 3.63
A 12 minute call will cost $3.63
A. 75 x 0.0016= .12 Has a value between 0 and 1
B. 3^5 / 3^-6 = 177147 Does not a value between 0 and 1
C. 1/4^3 x 1/4^2 = about 0.0009 Has a value between 0 and 1
D. -7^5 / -7^7 = about 0.02 Has a value between 0 and 1
First of all we want to find a common denominator so we can add them together.
40 is our Lowest Common Multiple.
5/8 = 25/40
1/5 = 8/40
25/40 + 8/40 = 33/40
