Answer:
The expression is y = 2x + 5. You could ride 6 rides with $17 dollars.
See Step by Step for scenario
Step-by-step explanation:
First, we must find the expression. 5 is our constant as we are charged this just to enter, and our cost increases by 2 for every x ride. So, our equation is:
y = 2x + 5.
If we have 17 dollars and want to know how many rides we can ride, we plug in 17 for y which is cost and solve.
17 = 2x + 5 | Subtract 5 from both sides
12 = 2x | Divide both sides by 2
6 = x, meaning you could ride 6 rides with $17.
Zane loves Skittles and M&M's. If a small pack of skittles costs 14 cents, and a small pack of M&M's costs 12 cents, how much will he spend to buy 6 packs of skittles and 4 packs of M&M's?
c = 14x + 12y
c = 14(6) + 12(4)
c = 84 + 48
c = 132, or $1.32
Zane will have to spend $1.32 to buy 6 packs of skittles and 4 packs of M&M's.
