It will be cost $ 42.39 for 27 slices of pizza
<h3>
Further Explanation</h3>
A slice of pizza = $1.57
27 slices of pizza = the number of pizza x price/slice
= 27 x 1.57
We are going to use standard algorithm to solve this multiplication
1.57 ⇒ 2 decimal places
<u> 27</u> x ⇒ 0 decimal place
1099
<u> 314 </u>+
42.39 ⇒ 2 decimal places
In decimal number multiplication, the process is the same with the whole number multiplication. Only always remember when to put the decimal point in the answer.

Still need to pay: $928
Step-by-step explanation:
4/5 --> 0.8 --> 80%
4640 x 0.8 --> 3712
Covered: $3712 (which is 80%)
Still need to pay: $928 (which is 20%)
• rearrange into form y = mx + c:
3y = 9 + x
y = 9/3 + x/3
y = 1/3x + 3
• substitute the gradient, 1/3, into the formula "m1 X m2 = -1" to find m2, which is the perpendicular of the gradient:
1/3 X m2 = -1
m2 = -3
• substitute x and y values of (-3, 2) into new equation, y = -3x + c, and rearrange, to find c and complete the equation:
2 = -3(-3) + c
2 = 9 + c
2 - 9 = c
c = -7
y = -3x - 7 is perpendicular to the line and passes through the point (-3, 2)
