Maryann is printing pictures from her recent trip to europe. an online print shop charges $0.15 per
4x6 inch print, along with a flat rate shipping charge of $3.00. if maryann has $35 to spend, how
many prints can she order?

213

Step-by-step explanation:

Let

The relationship between x and y can be represented through a linear equation.

y = a . x + b

where,

a is the slope

b is the y-intercept

The slope refers to the price per print, that is, a = $0.15/p.

Then,

y = $0.15/p . x + b

Even if x = 0, there is a fixed cost of $3.00 (y = $3.00). We can replace these values in the expression above.

$3.00 = $0.15/p . 0 + b

b = $3.00

The final equation is:

y = $0.15/p . x + $3.00

If MaryAnn has $35,

$35 = $0.15/p . x + $3.00

$32 = $0.15/p . x

x = 213 p

She can order 213 prints.

11

Step-by-step explanation:

0.15+3.00=3.15

35÷3.15=11.1111111111

round 11.1111111111 to 11

1 yard = 3 feet:

21 feet / 3 ft = 7 yards

12 feet  / 3 feet = 4 yards

7 x 4 = 28 square yards

he will need 28 tiles
