Answer:
is the expression that represent Markel's bill.
Step-by-step explanation:
We are given the following in the question:
Discount card provides a discount of 7%.
Let c be the cost of Markel's purchases, then,
Discount given to Markel =

Markel's bill =
= Cost price - Discount

is the expression that represent Markel's bill.
Let x = Snicker Bars
Let y = Wrapping paper
Therefore, solve as simultaneous equation:
16x + 4y = 132
20x + 6y = 190
Solve for y:
16x + 4y = 132
x = 132 - 4y/16
Substitute value of x into 20x + 6y = 190:
20(132 - 4y/16) + 6y = 190
2640 - 80y/16 + 6y = 190
2640 - 80y = 16(190 - 6y)
2640 - 80y = 3040 - 96y
96y - 80y = 3040 -2640
16y = 400
y = 400/16
y = 25
Substitute value of y = 25 in x = 132 - 4y/16 to find x:
x = 132 - 4(25)/16
x = 2
Therefore, the prices per Snickers snack bars is 2.
Answer:
210
Step-by-step explanation:
first I took 120 and divided by four to show how many cupcakes he can make in thirty minutes (.5 of an hour). this was 30. the reason we divided by four is because in two hours theres four halves.
120÷4=30 for half an hour
30x2=60 this is how many cupcakes he can make in one hour
since we already know how many he makes in two hours we're going to use that
120+60=180 (three hours)
120+60=180 (three hours)180+30 (half an hour) =210
