Answer:
water bottles = 3
Step-by-step explanation:
4x + 2x + 5 = 25
1. you need to get rid of the five, so subtract it from both sides
4x + 2x = 20 2. based on the amount you paid you need to find two multiplication problems that will amount to $20 (4x<u>3</u>= 12 <- - water 2x<u>4</u>=8 <-- cashews)
<u>underlined </u>= cost per item
Answer:
The better buy is 2 ice cream cones for $3.00
Step-by-step explanation:
Step one:
given
You can buy 2 ice cream cones for $3.00
let us solve for the unit cost
3/2= $1.5 per ice cream cone
Step two:
You can buy 4 ice cream cones for $7.00
let us solve for the unit cost
7/4= $1.75 per ice cream cone
The better buy is 2 ice cream cones for $3.00 because a cone is $0.25 less expensive than 4 ice cream cones for $7.00.
