Is 15b+4=25.6 equivalent to 0.6+15b+4=25.6

pychu [463]

No because
15b + 4 = 25.6
15b = 21.6
b = 1.44

0.6+15b+4 = 25.6
4.6 + 15b = 25.6
15b = 21
b = 1.4

The answers are not the same therefore they are not equivalent.

Answer:

Martha earns $65.6 over the weekend.

Step-by-step explanation:

Brownies sold by Martha on Saturday = 60

Cookies sold by Martha on Saturday = 42

Brownies sold by Martha on Sunday = 28

Cookies sold by Martha on Sunday = 54

Total brownies sold by Martha over the weekend = $60+28=88$

Total cookies sold by Martha over the weekend = $42+54=96$

Cost of a brownie = $0.20

Cost of a cookie = $0.50

Total cost of brownies sold over the weekend = $88\times \$0.20 = \$17.6$

Total cost of cookies sold over the weekend = $96\times \$0.50 = \$48$

∴ Total money Martha earned over the weekend = $\$17.6+\$48=\$65.6$ (Answer)

Sample space = {p, r, o, b, a, b, i, l, I, t, y} = 11 possible outcomes
1sr event: drawing an I ( there are 2 I); P(1st I) = 2/11
2nd event drawing also an i: This is a conditional probability, since one I has already been selected the remaining number of I is now 1, but also the sample space from previously 11 outcome has now 10 outcomes (one letter selected and not replaced)
2nd event : P(also one I) = 1/10
P(selecting one I AND another I) is 2/11 x 1/10

P(selecting one I AND another I) =2/110 = 0.018
