Larry needed to by 5 books at the same price. After he uses a $30 gift card, he can spend no more than $50. What is the maximum cost of each book that he can buy?

The maximum cost of each book will be $14 that Larry can buy.

Step-by-step explanation:

Given:

Gift card = $30

Maximum amount can be spend = $50

number of books need to buy = 5

We need to find maximum cost of each book.

Solution:

Let the cost of each book be 'x'.

So we can say that;

Sum of money of gift card and maximum money he can spend should be greater than or equal to number of books need to buy multiplied by cost of each book.

framing in  equation form we get;

Dividing both side by 5 we get;

Hence The maximum cost of each book will be $14 that Larry can buy.

option c) graph of line going through 1, 4 and 3, 10

step-by-step explanation:

let y equal to margo's coin collection

let x equal to number of years

at the begining x=0, y=1 → point=(x,y)→point=(0,1)

she adds 3 coins per year, then y=1+3x

at x=1, y=1+3(1)=1+3→y=4→point=(x,y)→point=(1,4)

at x=3, y=1+3(3)=1+9→y=10→point=(x,y)→point=(3,10)

the graph of line going through (1, 4) and (3, 10), then the option c is the correct.

noncoplanar points are points that do not lie on the same line.
