Answer:
25x + 65y = 80
Step-by-step explanation:
Total amount to be spent = $80
Maximum amount to be spent on music = $25
Maximum amount to be spent on books = $65
Let x represent music and y represent books
x(25) + y(65) = 80
25x + 65y = 80
The equation that represent the situation is
25x + 65y = 80
With multiple choice questions, I find it best to plug in on this one.
For a) x=2 and y=1 so, plug it into the equation.
1) -2(2) + 5(1) = 8 and than you check the other one
2) 2(2) + 2(1) = 6 if it works in both than that is your answer. If not than you try another choice until you get one that works in both equations.
Answer:
3. $2 per 1 pineapple
4. 35 miles per 1 hour
5. $7 per 1 hour
Step-by-step explanation:
A unit rate is the rate of measurement of an object per 1. Its feet per 1 hour or dollars per 1 item or 1 ounce. To find the unit rate divide the two measurements to a simpler fraction with 1 as the denominator or divide to a decimal if necessary.
Examples:
3. $8 / 4 pineapples = $2 per 1 pineapple
4. 105 miles / 3 hours = 35 miles per 1 hour
5. $35 / 5 hours = $7 per 1 hour
