A. The equation in slope-intercept form, relating the cost, y, to the number of nights stay, x is y = 755 + 101x.
B. The cost for 10 days is $1765.
<h3>How to calculate the value?</h3>
It should be noted that the information can be illustrated with an arithmetic sequence:
Smile Vacations is offering a 4-night Hawaiian vacation for $1,058. This will be illustrated as:
a + 3d = 1058
a = first term
d = common difference
The 7-night vacation for $1,361. This will be:
a + 6d = 1361
The equation will be represented as:
a + 3d = 1058
a + 6d = 1361
Subtract the equations:
3d = 303
Divide
d = 303/3
d = 101
Recall a + 3d = 1058
a + 3(101) = 1058
a + 303 = 1058
a = 1058 - 303
a = 755
The cost for 10 nights will be:
y = 755 + 101x.
y = 755 + 101(10)
y = 755 + 1010
y = 1765
