Hi there, the complete question is - <span>You wish to mentally estimate the total cost of items that have the following prices: $1.85, $.98, $3.49, $9.78, and $6.18. Rounding off the items to the nearest half dollar, your estimate of the total cost of these items is?
Add and estimate
</span> 2+1+3.5+10+6, so our estimate is $22.50.
Answer:
Step-by-step explanation:
The system of equations is:
● 3x + 2y = 7
● 2x + 4y = 8
Where x is the price of a single coffee and y is the price of a single coffee
We will solve this simultaneous equations using the graphing method:
The solutions is the intersection point of to the lines.
(Picture below)
The intersection point is (1.5,1.25)
Discount;
66 * 0.4 = 26.40
66 - 26.4 = 39.60
Tax;
66 * 0.05 = 3.30
Total Price:
39.60 + 3.30 = 42.90
$42.90
