Answer:

14a-8

Step-by-step explanation:

A perimeter is the sum of the length of each side. So we can find the perimeter by adding: (a+1)+(a+1)+(6a-5)+(6a-5).

Combine like terms to get: 14a+2-10 = 14a-8.

Without knowing what a is, the perimeter is 14a-8.

2(6a - 5) + 2(a + 1) =

= 12a - 10 + 2a + 2 =

= 12a + 2a - 10 + 2 = <u>1</u><u>4</u><u>a</u><u> </u><u>-</u><u> </u><u>8</u>

The students at Midtown Middle school sold flowers as a fundraiser in September and October. In October, they charged $1.50 for
swat32
Let the price of flowers in September be x, then (100 + 20)/100 * x = $1.50
120/100 * x = $1.50
1.2x = $1.50
x = $1.50/1.2 = $1.25
The price of flowers in September is $1.25

Total money realised in September = $1.25 x 900 = $1,125
40% earned = 0.4 x $1,125 = $450

Total money realised in October = $1.50 x 700 = $1,050
40% earned = 0.4 x $1,050 = $420

The class earned more money in September and they earned $30 more than in October.
