Matt spent $40 on jeans, $25 on a top, and $65 on shoes. He received €20 change from €150.

What percentage of his money did Matt spend on:
a) Jeans
b) A top
c) Shoes
d) All of his clothes?

Maya scored 32 out of 40 on a Math test and 41 out of 55 on a Science test. For which test did she score a lower percentage?

Matt spent 30.77% of his money on jeans, 19.23% on a top, and 50% on shoes. All his clothes account for 100% of the money spent. Maya scored lower on the Science test (74.54%) compared to the Math test (80%).

Explanation:

Matt spent a total of $40 (jeans) + $25 (top) + $65 (shoes) = $130. Since Matt received €20 change from €150, this means he spent €130, which is equivalent to $130. To find the percentage Matt spent on each item, we divide the cost of that item by total amount and multiply by 100.

a) Jeans: ($40 / $130) ˣ 100 = 30.77%

b) Top: ($25 / $130) ˣ 100 = 19.23%

c) Shoes: ($65 / $130) ˣ 100 = 50%

d) All clothes: 100% because it comprises all the items.

For Maya's scores in the Math and Science tests, we calculate the percentage similarly. The lower percentage score will indicate which test she performed worse on:

Math Test: (32/40) ˣ 100 = 80%

Science Test: (41/55) ˣ 100 = 74.54%

Therefore, Maya scored a lower percentage on the Science test.
