Answer:

Step-by-step explanation:

d + q = 27......d = 27 - q

0.10d + 0.25q = 4.35

0.10(27 - q) + 0.25q = 4.35

2.7 - 0.10q + 0.25q = 4.35

0.15q = 4.35 - 2.7

0.15q = 1.65

q = 1.65 / 0.15

q = 11 <=== 11 quarters

d + q = 27

d + 11 = 27

d = 27 - 11

d = 16 <===== 16 dimes

Tobias rented a kayak from a sports equipment store.
Ket [755]

Answer:

B

Step-by-step explanation:

Let x = every day he rented the kayak

Since the store charges $60 for each day, multiply x by 60 like this: 60x

They also have $25 on top of that; 60x + 25

This all has to equal $325; 60x + 25 = 325

To solve for x, subtract 25 from both sides

60x + 25 = 325

       - 25    - 25

60x = 300

Divide both sides by 60

60x/60 = 300/60

x = 5

This means Tobias rented the kayak for 5 days
