Daniel is paid $10 per week for selling newspaper subscriptions. He is also paid $3.50 for each new customer (x) that signs up f

Aliun [14]

Alright so, since it says that he eats at least $10 dollars no matter what we can basically leave that alone. next week have $3.50 for every new customer (x) so we could write this as $3.50x. and lastly we have Y the amount he will earn every week.

so the equation would be $10+$3.50x=Y.

if we had more information we might be able to solve for Y but since it doesn't tell us how many he sold we would leave it like that.

Under her cell phone plan, Lily pays a flat cost of $55.50 per month and $4 per

TEA [102]

Answer:

Equation : y = 4x + 55.50

x = 1.9 gigabytes

Step-by-step explanation:

Given that:

Flat fee per month = $55.50

Cost per gigabyte = $4

Let,

x be the number of gigabytes.

y be the total cost

y = 4x + 55.50

Lily wants to keep her bill $63.10

63.10 = 4x + 55.50

63.10 - 55.50 = 4x

4x = 7.60

Dividing both sides by 4

$\frac{4x}{4} = \frac{7.60}{4}\\x=1.9$

Hence,

Equation : y = 4x + 55.50

x = 1.9 gigabytes
