£399 is shared between Ann, Bill, Chloe and Dave.

lukranit [14]

Answer:

Ann=£38

Bill=£171

Chloe=£95

Dave=£95

Step-by-step explanation:

By the information provided we can create an equation:

$2x+9x+2*5x=399\\11x+10x=399\\21x=399\\x=19$

Now that we know x, we multiply it correspondingly.

For Ann -> 2*19=38

Bill -> 9*19= 171

Chloe and Dave have the exact same amount each (because they both have 2.5 times the amount Ann's money)

Chloe/ Dave -> 5*19=95 each.

9) A basic cell phone plan at Verizon Wireless costs $45 a month with an additional $0.10 per text message sent. AT&T charge

LenaWriter [7]

Number of tests made =x

Verzon C(x) = 45 + 0.1x => 45+0.1*1200 =165

AT & T C(y) = 30 + 0.13x=> 30 + 0.13*1200=186

For 1200 texts C(x) is less than C(y)

If the costs are to be the same then

45 + 0.1x = 30 + 0.13x

15=0.03x

15/0.03= x

500=x
