The phone company Blurizon has a monthly cellular plan where a customer pays a flat fee for unlimited voice calls and then a
certain amount per GB of data used. If a customer uses 10 GB,
the monthly cost will be 598. If the customer uses 32 GB, the
monthly cost will be $230.

A) Find an equation in the form y m. b, where r is the
number of GB of data used in a month and y is the total
monthly cost of the Blurizon plan.

y=

B) Use your equation to find the total monthly cost if 18 GB are
used.

If 18 GB are used, the total cost will be dollars.

it's equivalent, so we can say that its equal.

let's call the denominator x and the numerador is 18 less then denominator, x - 18.

multiply

2.x = 5.(x - 18)

2x = 5x - 90

90 = 5x - 2x

90 = 3x

x = 90/3

x = 30

where are the images of the functions i can only see the question you typed.

step-by-step explanation:

answer: c, the green line

step-by-step explanation:

there is no black line, eliminate b.

simple interest implies periodic payments, but the red line shows no payments, eliminate d.

simple interest has equal payments. if paid say every day, the graph is about a straight line (actually a stairstep).

the yellow line is not straight, eliminate a.

check: the green line is straight, answer is c.

simple interest with positive interest rate gives a straight line sloping up to the right. green line:

g(t) = $100 + ($200-$100) ÷ (20 years) × (t years)

= $100 + (4%/year) × ($100)(t years)

incidentally, the yellow line curving upward represents continuously compounded interest

y = $100 × 2^(t years / (14 assuming the yellow line hits $200 at 14 years. 2^0 is 1, so y(0) = $100; 2^(14/14) is 2, so y(14) = $200.

answer: 72: 111
