Amelia and Jayden work at a furniture store. Amelia is paid $185 per week plus 9.5% of her total sales in dollars, xx, which can
almond37 [142]

Answer:

The weekly sales must be $12,600

Step-by-step explanation:

if their pay is the same, the equations have to be equal

amelia = jayden

185 +.095x = 311 +.085x

subtract  .085x from each side

185 +.095x-.085x = 311 +.085x-.085x

185+.01x = 311

subtract 185 from each side

185-185+.01x = 311-185

.01x = 126

divide by .01

.01x/.01 = 126/.01

x = 12600

Brandon has a cup of quarters and dimes with the total value of $3.80. The number of quarters is 4 less than twice the number of
cestrela7 [59]

Answer:

Dimes = 8 and

Quarters = 12

Step-by-step explanation:

Total value = 380 cents

let dimes be x

quarters be 2x - 4

100 pennies = $1

1 dime = 10 pennies

1 quarter = 25 pennies

Therefore;

$ 3.78 = 378 pennies

10x+25(2x-4)=378

10x + 50 x - 100 = 378

60 x = 378 + 100

60 x = 478

     x = 478/60

        = 7.9667

        ≈ 8

Therefore;

Dimes = 8 and

Quarters = 12
