Which is the better buy? Find the unit rate for each meat. Show your work and explain reasoning.
KATRIN_1 [288]

You start by changing the fraction into a decimal.

4.5 lb. of ground beef= 16.11

6.25  lb. of ground turkey= 18.50

Next, you divide the amount they cost by the pounds to get the price per pound.

16.11÷4.5= 3.58

18.50÷6.25= 2.96

So, a pound of beef is $3.58, and a pound of turkey is $2.96.

The turkey is 62 cents less than the beef per pound.

That means the turkey is a better buy! :)


(Have a good day! :))

Please help i have been trying to figure this out for like an hour
KengaRu [80]

Answer:

B

Step-by-step explanation:

Since x varies directly as y, the ratio of x to y remains the same. Let the value of x when y=4 be a. Then we have

\dfrac {7 \frac12} {10} = \dfrac a4

We can cross multiply to get that

10a = 30, \text{so } \boxed{a=3}

Emilio’s family volunteers at the local soup
Mice21 [21]

Answer:

Emilio will have both activities again on the same day after 90 days from this Saturday.

Step-by-step explanation:

<em>To solve this question list the multiples of 30 and 9 to find the first common multiple because the two activities will happen again in </em><em>a number divisible by both 30 and 9.</em>

∵ The multiples of 30 are: 30, 60, 90, 120, ............

∵ The multiples of 9 are: 9, 18, 27, 36, 45, 54, 63, 72, 81, 90, 99, .....

→ The common multiple is 90

∴ The common multiple of 30 and 9 is 90

→ That means the activities will meet again after 90 days from

   this Saturday

Emilio will have both activities again on the same day after 90 days from this Saturday.
