Answer:

x = 26, 16

Step-by-step explanation:

( x-21) ^2 = 25

Take the square root of each side

sqrt(( x-21) ^2) = ±sqrt(25)

x-21 = ±5

Add 21 to each side

x-21+21 = 21±5

x = 21±5

x = 21+5 and x = 21-5

x = 26, 16

elena55 [62]

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)
