AnnZ [28]

Answer:

A. 3 weeks, $160

Step-by-step explanation:

If the value of y is same for both then we have equal right sides of equations

50x + 10 = 30x + 70

Solve this for x

50x - 30x = 70 - 10
20x = 60
x = 60/20
x = 3

Find the value of y

y = 50*3 + 10 = 150 + 10 = 160

Correct choice is A

Toni is shopping for clothes at the store she buys 8 shirts for $8.00 what is the unit rate for the shirts?

lozanna [386]

Answer:

$1.00

Step-by-step explanation:

The unit rate in this scenario would be $1.00 , meaning that Toni is paying $1.00 for every shirt. This can be calculated by dividing the total price that she is paying for the shirts by the total number of shirts that Toni is purchasing like so...

$8.00 / 8 = $1.00 per shirt

The unit rate is basically the value over the denominator of 1 which would be the case as seen above since $1 buys 1 shirt ( $\frac{1 dollar}{1 shirt}$ ) as opposed to $8 dollars 8 shirts ( $\frac{8 dollars}{8 shirts}$ ) as mentioned in the question.
