Rosie has £15 to spend on pens and pencils. She has to buy the same number of pens as pencils.
What is the greatest number of pens she can buy?
Pens cost £0.32
Pencils cost £0.08

37

Step-by-step explanation:

Since you have to have the same amount of pens and pencils, they will have the same variable.  The variable, x, represents the amount.  Multiply x by the costs and add the two costs together.  Set it equal to 15 and solve.

0.32x + 0.08x = 15

0.40x = 15

(0.40x)/0.40 = 15/0.40

x = 37.5

Since she can't spend more than £15, round your answer down.  This gives you 37.  She can buy 37 pens.

i think it's either c or d

step-by-step explanation: the entire question is extremely odd. 04 obviously refers to the interest rate. honestly i will say the answer is c. because the (2 x 12) part would mean it's compounded semiannually. i'll say choose c.

to find the total number of combinations, multiply the quantity of each item by each other:

2 pairs of shoes x 3 pairs of shorts = 6 different combinations.
