Caterpillars turn into butterflies after pupating. A scientist investigated the effect of temperature on the number of days taken for a caterpillar to become a butterfly. The scientist collected 120 caterpillars of one species of butterfly. All the caterpillars were the same age. Four glasshouses were prepared and each was maintained at a different temperature. 30 caterpillars were placed in each glasshouse. Each group of caterpillars was provided with the same mass of food. The scientist observed the caterpillars in the glasshouses and recorded the number of caterpillars remaining at each temperature. Table 2.1 shows the scientist's results at 30 days and 60 days. Calculate the percentage change in the number of caterpillars remaining between 30 days and 60 days when the temperature was $$$15^{\circ} \mathrm{C}$$$. Give your answer to one decimal place. Space for working. ........................................................ $$$\%$$$
